Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512676, here are decompositions:

3 + 31512673 = 31512676
59 + 31512617 = 31512676
89 + 31512587 = 31512676
197 + 31512479 = 31512676
317 + 31512359 = 31512676
467 + 31512209 = 31512676
557 + 31512119 = 31512676
563 + 31512113 = 31512676

Showing the first eight; more decompositions exist.
