Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460182, here are decompositions:

53 + 31460129 = 31460182
233 + 31459949 = 31460182
251 + 31459931 = 31460182
353 + 31459829 = 31460182
449 + 31459733 = 31460182
503 + 31459679 = 31460182
521 + 31459661 = 31460182
563 + 31459619 = 31460182

Showing the first eight; more decompositions exist.
