Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607560, here are decompositions:

29 + 31607531 = 31607560
71 + 31607489 = 31607560
113 + 31607447 = 31607560
137 + 31607423 = 31607560
197 + 31607363 = 31607560
233 + 31607327 = 31607560
251 + 31607309 = 31607560
263 + 31607297 = 31607560

Showing the first eight; more decompositions exist.
