Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612956, here are decompositions:

5 + 31612951 = 31612956
17 + 31612939 = 31612956
43 + 31612913 = 31612956
83 + 31612873 = 31612956
103 + 31612853 = 31612956
197 + 31612759 = 31612956
223 + 31612733 = 31612956
227 + 31612729 = 31612956

Showing the first eight; more decompositions exist.
