Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494710, here are decompositions:

3 + 31494707 = 31494710
19 + 31494691 = 31494710
31 + 31494679 = 31494710
67 + 31494643 = 31494710
73 + 31494637 = 31494710
127 + 31494583 = 31494710
157 + 31494553 = 31494710
241 + 31494469 = 31494710

Showing the first eight; more decompositions exist.
