In 1742, a German amateur mathematician named Christian Goldbach wrote
to Leonhard Euler with the following conjecture:

* Every number greater than 2 can be written as the sum of three
prime numbers. *

In his conjecture, Goldbach was considering 1 as a prime number. By
convention we no longer consider 1 as a prime number. And Euler later
modified the conjecture as follows:

* Every even number greater than or equal to 4 can be expressed as
the sum of two prime numbers. *

For example:

- 8 = 3 + 5
- 20 = 3 + 17 = 7 + 13
- 42 = 5 + 37 = 11 + 31 = 13 + 29 = 19 + 23

There is no formal proof of this conjecture. However, we can verify
Goldbach's conjecture in certain ranges. For this programming assignment
you are asked to verify Goldbach's conjecture in the range 4 through
100 (inclusive). Your output will print out all the even numbers in the
range 4 to 100 (both inclusive) in the form * n = a + b*, where
*a* and *b* are prime numbers and a <= b. Each even number
should be on a separate line followed by ** all** possible unique
pairs of prime numbers. Your sample output should look like this:

4 = 2 + 2 6 = 3 + 3 8 = 3 + 5 10 = 3 + 7 = 5 + 5 .... .... 100 = ....

Your program should have a good, clean logical structure. You **must**
make use of function *isPrime()* that we developed in class. We will
be looking at good documentation, descriptive variable names, and adherence
to the coding convention mentioned below. Your file *Goldbach.py* will
have the following header:

Use the turnin
program to submit your **Goldbach.py** file.
The TA should receive your work by 11 PM on Friday, 19 July 2013.
There will be substantial penalties if you do not adhere to the
guidelines.

- Your Python program should have the header with the proper documentation.
- Your code must run before submission.
- You should be submitting your file through the web based
*turnin*program. We will not accept files e-mailed to us. - Here is the Grading Criteria.
