Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571514, here are decompositions:

17 + 31571497 = 31571514
47 + 31571467 = 31571514
61 + 31571453 = 31571514
67 + 31571447 = 31571514
101 + 31571413 = 31571514
131 + 31571383 = 31571514
167 + 31571347 = 31571514
181 + 31571333 = 31571514

Showing the first eight; more decompositions exist.
