Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571682, here are decompositions:

29 + 31571653 = 31571682
31 + 31571651 = 31571682
61 + 31571621 = 31571682
71 + 31571611 = 31571682
113 + 31571569 = 31571682
229 + 31571453 = 31571682
269 + 31571413 = 31571682
283 + 31571399 = 31571682

Showing the first eight; more decompositions exist.
