Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612216, here are decompositions:

17 + 31612199 = 31612216
107 + 31612109 = 31612216
137 + 31612079 = 31612216
173 + 31612043 = 31612216
347 + 31611869 = 31612216
479 + 31611737 = 31612216
557 + 31611659 = 31612216
569 + 31611647 = 31612216

Showing the first eight; more decompositions exist.
