Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608760, here are decompositions:

3 + 31608757 = 31608760
11 + 31608749 = 31608760
23 + 31608737 = 31608760
47 + 31608713 = 31608760
173 + 31608587 = 31608760
233 + 31608527 = 31608760
263 + 31608497 = 31608760
311 + 31608449 = 31608760

Showing the first eight; more decompositions exist.
