Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496610, here are decompositions:

11 + 31496599 = 31496610
17 + 31496593 = 31496610
23 + 31496587 = 31496610
37 + 31496573 = 31496610
43 + 31496567 = 31496610
59 + 31496551 = 31496610
71 + 31496539 = 31496610
73 + 31496537 = 31496610

Showing the first eight; more decompositions exist.
