Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612664, here are decompositions:

3 + 31612661 = 31612664
37 + 31612627 = 31612664
43 + 31612621 = 31612664
67 + 31612597 = 31612664
151 + 31612513 = 31612664
211 + 31612453 = 31612664
241 + 31612423 = 31612664
283 + 31612381 = 31612664

Showing the first eight; more decompositions exist.
