Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566504, here are decompositions:

7 + 31566497 = 31566504
17 + 31566487 = 31566504
23 + 31566481 = 31566504
31 + 31566473 = 31566504
61 + 31566443 = 31566504
107 + 31566397 = 31566504
127 + 31566377 = 31566504
157 + 31566347 = 31566504

Showing the first eight; more decompositions exist.
