Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607766, here are decompositions:

19 + 31607747 = 31607766
79 + 31607687 = 31607766
83 + 31607683 = 31607766
137 + 31607629 = 31607766
167 + 31607599 = 31607766
263 + 31607503 = 31607766
277 + 31607489 = 31607766
293 + 31607473 = 31607766

Showing the first eight; more decompositions exist.
