Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456276, here are decompositions:

17 + 31456259 = 31456276
29 + 31456247 = 31456276
83 + 31456193 = 31456276
113 + 31456163 = 31456276
197 + 31456079 = 31456276
263 + 31456013 = 31456276
317 + 31455959 = 31456276
347 + 31455929 = 31456276

Showing the first eight; more decompositions exist.
