Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588528, here are decompositions:

5 + 31588523 = 31588528
89 + 31588439 = 31588528
197 + 31588331 = 31588528
281 + 31588247 = 31588528
467 + 31588061 = 31588528
509 + 31588019 = 31588528
617 + 31587911 = 31588528
761 + 31587767 = 31588528

Showing the first eight; more decompositions exist.
