Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571710, here are decompositions:

3 + 31571707 = 31571710
11 + 31571699 = 31571710
59 + 31571651 = 31571710
83 + 31571627 = 31571710
89 + 31571621 = 31571710
257 + 31571453 = 31571710
263 + 31571447 = 31571710
311 + 31571399 = 31571710

Showing the first eight; more decompositions exist.
