Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590682, here are decompositions:

23 + 31590659 = 31590682
89 + 31590593 = 31590682
131 + 31590551 = 31590682
239 + 31590443 = 31590682
269 + 31590413 = 31590682
281 + 31590401 = 31590682
311 + 31590371 = 31590682
419 + 31590263 = 31590682

Showing the first eight; more decompositions exist.
