Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588510, here are decompositions:

17 + 31588493 = 31588510
47 + 31588463 = 31588510
71 + 31588439 = 31588510
179 + 31588331 = 31588510
197 + 31588313 = 31588510
257 + 31588253 = 31588510
263 + 31588247 = 31588510
311 + 31588199 = 31588510

Showing the first eight; more decompositions exist.
