Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612862, here are decompositions:

31 + 31612831 = 31612862
103 + 31612759 = 31612862
109 + 31612753 = 31612862
199 + 31612663 = 31612862
241 + 31612621 = 31612862
331 + 31612531 = 31612862
349 + 31612513 = 31612862
409 + 31612453 = 31612862

Showing the first eight; more decompositions exist.
