Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607764, here are decompositions:

17 + 31607747 = 31607764
47 + 31607717 = 31607764
233 + 31607531 = 31607764
317 + 31607447 = 31607764
401 + 31607363 = 31607764
467 + 31607297 = 31607764
557 + 31607207 = 31607764
563 + 31607201 = 31607764

Showing the first eight; more decompositions exist.
