Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463776, here are decompositions:

17 + 31463759 = 31463776
59 + 31463717 = 31463776
257 + 31463519 = 31463776
269 + 31463507 = 31463776
293 + 31463483 = 31463776
317 + 31463459 = 31463776
347 + 31463429 = 31463776
389 + 31463387 = 31463776

Showing the first eight; more decompositions exist.
