Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596490, here are decompositions:

17 + 31596473 = 31596490
53 + 31596437 = 31596490
71 + 31596419 = 31596490
89 + 31596401 = 31596490
173 + 31596317 = 31596490
179 + 31596311 = 31596490
197 + 31596293 = 31596490
281 + 31596209 = 31596490

Showing the first eight; more decompositions exist.
