Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494968, here are decompositions:

19 + 31494949 = 31494968
31 + 31494937 = 31494968
61 + 31494907 = 31494968
151 + 31494817 = 31494968
199 + 31494769 = 31494968
277 + 31494691 = 31494968
331 + 31494637 = 31494968
499 + 31494469 = 31494968

Showing the first eight; more decompositions exist.
