Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510364, here are decompositions:

43 + 31510321 = 31510364
271 + 31510093 = 31510364
373 + 31509991 = 31510364
397 + 31509967 = 31510364
547 + 31509817 = 31510364
601 + 31509763 = 31510364
607 + 31509757 = 31510364
673 + 31509691 = 31510364

Showing the first eight; more decompositions exist.
