Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612076, here are decompositions:

7 + 31612069 = 31612076
79 + 31611997 = 31612076
193 + 31611883 = 31612076
367 + 31611709 = 31612076
373 + 31611703 = 31612076
409 + 31611667 = 31612076
499 + 31611577 = 31612076
523 + 31611553 = 31612076

Showing the first eight; more decompositions exist.
