Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612848, here are decompositions:

17 + 31612831 = 31612848
89 + 31612759 = 31612848
101 + 31612747 = 31612848
109 + 31612739 = 31612848
181 + 31612667 = 31612848
227 + 31612621 = 31612848
229 + 31612619 = 31612848
251 + 31612597 = 31612848

Showing the first eight; more decompositions exist.
