Cuban Primes 1

A cuban prime (from the role cubes (third powers) play in the equations) is a prime number that is a solution to one of two different specific equations involving third powers of x and y. The first of these equations is: p=(x3-y3)/(x-y), x=y+1, y>0

The general cuban prime of this kind can be rewritten as ((y+1)3-y3)/(y+1-y) which simplifies to 3y2+3y+1. This is exactly the general form of a centered hexagonal number; that is, all of these cuban primes are centered hexagonal.
