Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588804, here are decompositions:

131 + 31588673 = 31588804
173 + 31588631 = 31588804
197 + 31588607 = 31588804
281 + 31588523 = 31588804
311 + 31588493 = 31588804
491 + 31588313 = 31588804
557 + 31588247 = 31588804
647 + 31588157 = 31588804

Showing the first eight; more decompositions exist.
