Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456456, here are decompositions:

137 + 31456319 = 31456456
179 + 31456277 = 31456456
197 + 31456259 = 31456456
257 + 31456199 = 31456456
263 + 31456193 = 31456456
293 + 31456163 = 31456456
389 + 31456067 = 31456456
443 + 31456013 = 31456456

Showing the first eight; more decompositions exist.
