Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510846, here are decompositions:

47 + 31510799 = 31510846
83 + 31510763 = 31510846
89 + 31510757 = 31510846
167 + 31510679 = 31510846
293 + 31510553 = 31510846
359 + 31510487 = 31510846
443 + 31510403 = 31510846
449 + 31510397 = 31510846

Showing the first eight; more decompositions exist.
