Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474822, here are decompositions:

59 + 31474763 = 31474822
89 + 31474733 = 31474822
101 + 31474721 = 31474822
131 + 31474691 = 31474822
149 + 31474673 = 31474822
251 + 31474571 = 31474822
263 + 31474559 = 31474822
389 + 31474433 = 31474822

Showing the first eight; more decompositions exist.
