Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566414, here are decompositions:

17 + 31566397 = 31566414
31 + 31566383 = 31566414
37 + 31566377 = 31566414
67 + 31566347 = 31566414
97 + 31566317 = 31566414
127 + 31566287 = 31566414
163 + 31566251 = 31566414
167 + 31566247 = 31566414

Showing the first eight; more decompositions exist.
