Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612064, here are decompositions:

67 + 31611997 = 31612064
157 + 31611907 = 31612064
181 + 31611883 = 31612064
223 + 31611841 = 31612064
307 + 31611757 = 31612064
331 + 31611733 = 31612064
397 + 31611667 = 31612064
457 + 31611607 = 31612064

Showing the first eight; more decompositions exist.
