Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612966, here are decompositions:

5 + 31612961 = 31612966
53 + 31612913 = 31612966
113 + 31612853 = 31612966
227 + 31612739 = 31612966
233 + 31612733 = 31612966
239 + 31612727 = 31612966
347 + 31612619 = 31612966
383 + 31612583 = 31612966

Showing the first eight; more decompositions exist.
