Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612352, here are decompositions:

43 + 31612309 = 31612352
151 + 31612201 = 31612352
271 + 31612081 = 31612352
283 + 31612069 = 31612352
523 + 31611829 = 31612352
619 + 31611733 = 31612352
643 + 31611709 = 31612352
769 + 31611583 = 31612352

Showing the first eight; more decompositions exist.
