Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627560, here are decompositions:

17 + 31627543 = 31627560
23 + 31627537 = 31627560
59 + 31627501 = 31627560
149 + 31627411 = 31627560
227 + 31627333 = 31627560
241 + 31627319 = 31627560
257 + 31627303 = 31627560
271 + 31627289 = 31627560

Showing the first eight; more decompositions exist.
