Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588586, here are decompositions:

103 + 31588483 = 31588586
229 + 31588357 = 31588586
283 + 31588303 = 31588586
457 + 31588129 = 31588586
499 + 31588087 = 31588586
607 + 31587979 = 31588586
643 + 31587943 = 31588586
709 + 31587877 = 31588586

Showing the first eight; more decompositions exist.
