Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510376, here are decompositions:

13 + 31510363 = 31510376
67 + 31510309 = 31510376
283 + 31510093 = 31510376
367 + 31510009 = 31510376
409 + 31509967 = 31510376
463 + 31509913 = 31510376
487 + 31509889 = 31510376
613 + 31509763 = 31510376

Showing the first eight; more decompositions exist.
