[CSC 330] Questions about Integer Size

Class -- one question I keep getting relates to the largest integer to
be input into your Goldbach weak conjecture algorithm.  To make this
simple lets keep it to the maximum size of a signed integer in gcc on
cobra -- 2147483647.   That should make it also work without too much
difficulty across all of the other programming languages we will be using.

I know that there are 105097566 prime numbers - and some of you are
focusing on the "worst possible base" of having a huge number as
input.   My recommendation is to not do that.  Get code working for
small cases and then you can focus on improving it for larger values.
