Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610590, here are decompositions:

3 + 31610587 = 31610590
17 + 31610573 = 31610590
29 + 31610561 = 31610590
71 + 31610519 = 31610590
197 + 31610393 = 31610590
227 + 31610363 = 31610590
251 + 31610339 = 31610590
257 + 31610333 = 31610590

Showing the first eight; more decompositions exist.
