Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496660, here are decompositions:

61 + 31496599 = 31496660
67 + 31496593 = 31496660
73 + 31496587 = 31496660
109 + 31496551 = 31496660
211 + 31496449 = 31496660
241 + 31496419 = 31496660
271 + 31496389 = 31496660
331 + 31496329 = 31496660

Showing the first eight; more decompositions exist.
