Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507414, here are decompositions:

11 + 31507403 = 31507414
47 + 31507367 = 31507414
53 + 31507361 = 31507414
131 + 31507283 = 31507414
233 + 31507181 = 31507414
503 + 31506911 = 31507414
593 + 31506821 = 31507414
773 + 31506641 = 31507414

Showing the first eight; more decompositions exist.
