Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612814, here are decompositions:

61 + 31612753 = 31612814
67 + 31612747 = 31612814
151 + 31612663 = 31612814
193 + 31612621 = 31612814
241 + 31612573 = 31612814
283 + 31612531 = 31612814
433 + 31612381 = 31612814
463 + 31612351 = 31612814

Showing the first eight; more decompositions exist.
