Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612950, here are decompositions:

11 + 31612939 = 31612950
37 + 31612913 = 31612950
59 + 31612891 = 31612950
97 + 31612853 = 31612950
191 + 31612759 = 31612950
197 + 31612753 = 31612950
211 + 31612739 = 31612950
223 + 31612727 = 31612950

Showing the first eight; more decompositions exist.
