Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495414, here are decompositions:

11 + 31495403 = 31495414
47 + 31495367 = 31495414
53 + 31495361 = 31495414
173 + 31495241 = 31495414
227 + 31495187 = 31495414
257 + 31495157 = 31495414
491 + 31494923 = 31495414
647 + 31494767 = 31495414

Showing the first eight; more decompositions exist.
