Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474962, here are decompositions:

31 + 31474931 = 31474962
89 + 31474873 = 31474962
179 + 31474783 = 31474962
199 + 31474763 = 31474962
229 + 31474733 = 31474962
241 + 31474721 = 31474962
269 + 31474693 = 31474962
271 + 31474691 = 31474962

Showing the first eight; more decompositions exist.
