Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490682, here are decompositions:

5 + 31490677 = 31490682
23 + 31490659 = 31490682
31 + 31490651 = 31490682
53 + 31490629 = 31490682
59 + 31490623 = 31490682
61 + 31490621 = 31490682
73 + 31490609 = 31490682
89 + 31490593 = 31490682

Showing the first eight; more decompositions exist.
