Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486662, here are decompositions:

5 + 31486657 = 31486662
19 + 31486643 = 31486662
23 + 31486639 = 31486662
29 + 31486633 = 31486662
59 + 31486603 = 31486662
113 + 31486549 = 31486662
199 + 31486463 = 31486662
211 + 31486451 = 31486662

Showing the first eight; more decompositions exist.
