Even number sum of two primes
WebOf the primes occurring in this decomposition, 2, 5, and 7, only 7 is congruent to 3 modulo 4. Its exponent in the decomposition, 2, is even. Therefore, the theorem states that it is expressible as the sum of two squares. Indeed, 2450 = 72+ 492. The prime decomposition of the number 3430 is 2 · 5 · 73.
