Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590256, here are decompositions:

107 + 31590149 = 31590256
167 + 31590089 = 31590256
389 + 31589867 = 31590256
479 + 31589777 = 31590256
563 + 31589693 = 31590256
743 + 31589513 = 31590256
773 + 31589483 = 31590256
953 + 31589303 = 31590256

Showing the first eight; more decompositions exist.
