Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486674, here are decompositions:

13 + 31486661 = 31486674
17 + 31486657 = 31486674
31 + 31486643 = 31486674
41 + 31486633 = 31486674
47 + 31486627 = 31486674
61 + 31486613 = 31486674
71 + 31486603 = 31486674
103 + 31486571 = 31486674

Showing the first eight; more decompositions exist.
