Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612364, here are decompositions:

13 + 31612351 = 31612364
163 + 31612201 = 31612364
283 + 31612081 = 31612364
367 + 31611997 = 31612364
457 + 31611907 = 31612364
523 + 31611841 = 31612364
547 + 31611817 = 31612364
607 + 31611757 = 31612364

Showing the first eight; more decompositions exist.
