Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588564, here are decompositions:

3 + 31588561 = 31588564
41 + 31588523 = 31588564
71 + 31588493 = 31588564
101 + 31588463 = 31588564
197 + 31588367 = 31588564
233 + 31588331 = 31588564
251 + 31588313 = 31588564
257 + 31588307 = 31588564

Showing the first eight; more decompositions exist.
