Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612196, here are decompositions:

127 + 31612069 = 31612196
199 + 31611997 = 31612196
313 + 31611883 = 31612196
367 + 31611829 = 31612196
379 + 31611817 = 31612196
439 + 31611757 = 31612196
463 + 31611733 = 31612196
487 + 31611709 = 31612196

Showing the first eight; more decompositions exist.
