Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588534, here are decompositions:

11 + 31588523 = 31588534
41 + 31588493 = 31588534
71 + 31588463 = 31588534
167 + 31588367 = 31588534
227 + 31588307 = 31588534
281 + 31588253 = 31588534
431 + 31588103 = 31588534
641 + 31587893 = 31588534

Showing the first eight; more decompositions exist.
