Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494716, here are decompositions:

3 + 31494713 = 31494716
37 + 31494679 = 31494716
73 + 31494643 = 31494716
79 + 31494637 = 31494716
163 + 31494553 = 31494716
277 + 31494439 = 31494716
619 + 31494097 = 31494716
727 + 31493989 = 31494716

Showing the first eight; more decompositions exist.
