Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469118, here are decompositions:

17 + 31469101 = 31469118
151 + 31468967 = 31469118
199 + 31468919 = 31469118
257 + 31468861 = 31469118
269 + 31468849 = 31469118
419 + 31468699 = 31469118
487 + 31468631 = 31469118
521 + 31468597 = 31469118

Showing the first eight; more decompositions exist.
