Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587596, here are decompositions:

163 + 31587433 = 31587596
199 + 31587397 = 31587596
307 + 31587289 = 31587596
373 + 31587223 = 31587596
577 + 31587019 = 31587596
727 + 31586869 = 31587596
757 + 31586839 = 31587596
787 + 31586809 = 31587596

Showing the first eight; more decompositions exist.
