Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612232, here are decompositions:

31 + 31612201 = 31612232
151 + 31612081 = 31612232
163 + 31612069 = 31612232
349 + 31611883 = 31612232
499 + 31611733 = 31612232
523 + 31611709 = 31612232
829 + 31611403 = 31612232
853 + 31611379 = 31612232

Showing the first eight; more decompositions exist.
