Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588304, here are decompositions:

37 + 31588267 = 31588304
103 + 31588201 = 31588304
487 + 31587817 = 31588304
523 + 31587781 = 31588304
607 + 31587697 = 31588304
877 + 31587427 = 31588304
883 + 31587421 = 31588304
907 + 31587397 = 31588304

Showing the first eight; more decompositions exist.
