Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612982, here are decompositions:

13 + 31612969 = 31612982
31 + 31612951 = 31612982
43 + 31612939 = 31612982
109 + 31612873 = 31612982
151 + 31612831 = 31612982
223 + 31612759 = 31612982
229 + 31612753 = 31612982
409 + 31612573 = 31612982

Showing the first eight; more decompositions exist.
