Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588426, here are decompositions:

59 + 31588367 = 31588426
113 + 31588313 = 31588426
173 + 31588253 = 31588426
179 + 31588247 = 31588426
227 + 31588199 = 31588426
269 + 31588157 = 31588426
503 + 31587923 = 31588426
647 + 31587779 = 31588426

Showing the first eight; more decompositions exist.
