Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612748, here are decompositions:

19 + 31612729 = 31612748
127 + 31612621 = 31612748
151 + 31612597 = 31612748
367 + 31612381 = 31612748
379 + 31612369 = 31612748
397 + 31612351 = 31612748
439 + 31612309 = 31612748
547 + 31612201 = 31612748

Showing the first eight; more decompositions exist.
