Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495456, here are decompositions:

53 + 31495403 = 31495456
89 + 31495367 = 31495456
257 + 31495199 = 31495456
269 + 31495187 = 31495456
347 + 31495109 = 31495456
569 + 31494887 = 31495456
647 + 31494809 = 31495456
719 + 31494737 = 31495456

Showing the first eight; more decompositions exist.
