Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612112, here are decompositions:

3 + 31612109 = 31612112
31 + 31612081 = 31612112
43 + 31612069 = 31612112
229 + 31611883 = 31612112
271 + 31611841 = 31612112
283 + 31611829 = 31612112
379 + 31611733 = 31612112
409 + 31611703 = 31612112

Showing the first eight; more decompositions exist.
