Prove that the numbers that begin with 1 and end with 1, with any number of 2s in the middle, and all 1s and 2s separated by 00 are composite.

For example:
1002001
1002002001,
1002002002001,
1002002002002001

I wasn't talking to you. I WAS TALKING TO NICK!!!

:-) j/k

However, I'm not sure what you're saying....
1001³ = 1001 x 1002001, but does not equal 1002002001.
