Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610800, here are decompositions:

29 + 31610771 = 31610800
59 + 31610741 = 31610800
71 + 31610729 = 31610800
227 + 31610573 = 31610800
239 + 31610561 = 31610800
281 + 31610519 = 31610800
461 + 31610339 = 31610800
467 + 31610333 = 31610800

Showing the first eight; more decompositions exist.
