Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496630, here are decompositions:

19 + 31496611 = 31496630
31 + 31496599 = 31496630
37 + 31496593 = 31496630
43 + 31496587 = 31496630
79 + 31496551 = 31496630
181 + 31496449 = 31496630
211 + 31496419 = 31496630
241 + 31496389 = 31496630

Showing the first eight; more decompositions exist.
