Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610560, here are decompositions:

41 + 31610519 = 31610560
167 + 31610393 = 31610560
197 + 31610363 = 31610560
227 + 31610333 = 31610560
269 + 31610291 = 31610560
281 + 31610279 = 31610560
347 + 31610213 = 31610560
389 + 31610171 = 31610560

Showing the first eight; more decompositions exist.
