Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612712, here are decompositions:

139 + 31612573 = 31612712
181 + 31612531 = 31612712
199 + 31612513 = 31612712
283 + 31612429 = 31612712
331 + 31612381 = 31612712
349 + 31612363 = 31612712
631 + 31612081 = 31612712
643 + 31612069 = 31612712

Showing the first eight; more decompositions exist.
