Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474984, here are decompositions:

3 + 31474981 = 31474984
53 + 31474931 = 31474984
251 + 31474733 = 31474984
263 + 31474721 = 31474984
293 + 31474691 = 31474984
311 + 31474673 = 31474984
383 + 31474601 = 31474984
503 + 31474481 = 31474984

Showing the first eight; more decompositions exist.
