Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607960, here are decompositions:

103 + 31607857 = 31607960
271 + 31607689 = 31607960
277 + 31607683 = 31607960
331 + 31607629 = 31607960
379 + 31607581 = 31607960
409 + 31607551 = 31607960
457 + 31607503 = 31607960
487 + 31607473 = 31607960

Showing the first eight; more decompositions exist.
