Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534750, here are decompositions:

11 + 31534739 = 31534750
41 + 31534709 = 31534750
59 + 31534691 = 31534750
113 + 31534637 = 31534750
197 + 31534553 = 31534750
257 + 31534493 = 31534750
263 + 31534487 = 31534750
293 + 31534457 = 31534750

Showing the first eight; more decompositions exist.
