Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475014, here are decompositions:

5 + 31475009 = 31475014
17 + 31474997 = 31475014
83 + 31474931 = 31475014
251 + 31474763 = 31475014
281 + 31474733 = 31475014
293 + 31474721 = 31475014
443 + 31474571 = 31475014
617 + 31474397 = 31475014

Showing the first eight; more decompositions exist.
