Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474774, here are decompositions:

11 + 31474763 = 31474774
41 + 31474733 = 31474774
53 + 31474721 = 31474774
83 + 31474691 = 31474774
101 + 31474673 = 31474774
173 + 31474601 = 31474774
197 + 31474577 = 31474774
293 + 31474481 = 31474774

Showing the first eight; more decompositions exist.
