Answer: 6857

A further optimization would be to store known primes in the table and check
against those.
Optimized Problem 3 so that it only checks odd numbers.

Changed the algorithm to start checking at 3 and only check odd numbers hence-
forth for primality. This led to a 46.717% increase in performance.

Need to look at optimizing this. Takes ~3.67 seconds to find a solution as is.
I will backburner a better algorithm for now.
