Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460546, here are decompositions:

37 + 31460509 = 31460546
199 + 31460347 = 31460546
283 + 31460263 = 31460546
349 + 31460197 = 31460546
373 + 31460173 = 31460546
379 + 31460167 = 31460546
409 + 31460137 = 31460546
547 + 31459999 = 31460546

Showing the first eight; more decompositions exist.
