Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456796, here are decompositions:

127 + 31456669 = 31456796
157 + 31456639 = 31456796
199 + 31456597 = 31456796
367 + 31456429 = 31456796
577 + 31456219 = 31456796
673 + 31456123 = 31456796
907 + 31455889 = 31456796
919 + 31455877 = 31456796

Showing the first eight; more decompositions exist.
