Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510636, here are decompositions:

5 + 31510631 = 31510636
83 + 31510553 = 31510636
149 + 31510487 = 31510636
233 + 31510403 = 31510636
239 + 31510397 = 31510636
317 + 31510319 = 31510636
419 + 31510217 = 31510636
449 + 31510187 = 31510636

Showing the first eight; more decompositions exist.
