Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476964, here are decompositions:

5 + 31476959 = 31476964
17 + 31476947 = 31476964
47 + 31476917 = 31476964
83 + 31476881 = 31476964
353 + 31476611 = 31476964
503 + 31476461 = 31476964
593 + 31476371 = 31476964
647 + 31476317 = 31476964

Showing the first eight; more decompositions exist.
