Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566514, here are decompositions:

17 + 31566497 = 31566514
41 + 31566473 = 31566514
71 + 31566443 = 31566514
131 + 31566383 = 31566514
137 + 31566377 = 31566514
167 + 31566347 = 31566514
197 + 31566317 = 31566514
227 + 31566287 = 31566514

Showing the first eight; more decompositions exist.
