Abstract

Integer structure theory is used to analyse the factors of sums and differences of two identical powers of two integers, x and y. For instance, the sum of two identical powers, m, cannot form primes when m is odd or when m is even if the powers are odd and of the form m/2. The expanded forms of the factors indicate why the structure acts against the sum ever equalling an identical power. The difference of odd powers can yield primes when xy = 1. The difference of even powers cannot yield primes whereas the sum can when m/2n is even. However, x2y2 can equal a prime when xy = 1.
