Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494704, here are decompositions:

13 + 31494691 = 31494704
61 + 31494643 = 31494704
67 + 31494637 = 31494704
151 + 31494553 = 31494704
277 + 31494427 = 31494704
457 + 31494247 = 31494704
463 + 31494241 = 31494704
547 + 31494157 = 31494704

Showing the first eight; more decompositions exist.
