Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456996, here are decompositions:

47 + 31456949 = 31456996
59 + 31456937 = 31456996
113 + 31456883 = 31456996
167 + 31456829 = 31456996
227 + 31456769 = 31456996
257 + 31456739 = 31456996
269 + 31456727 = 31456996
293 + 31456703 = 31456996

Showing the first eight; more decompositions exist.
