Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588036, here are decompositions:

17 + 31588019 = 31588036
113 + 31587923 = 31588036
257 + 31587779 = 31588036
269 + 31587767 = 31588036
419 + 31587617 = 31588036
449 + 31587587 = 31588036
509 + 31587527 = 31588036
563 + 31587473 = 31588036

Showing the first eight; more decompositions exist.
