Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612796, here are decompositions:

37 + 31612759 = 31612796
43 + 31612753 = 31612796
67 + 31612729 = 31612796
199 + 31612597 = 31612796
223 + 31612573 = 31612796
283 + 31612513 = 31612796
367 + 31612429 = 31612796
373 + 31612423 = 31612796

Showing the first eight; more decompositions exist.
