Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510594, here are decompositions:

41 + 31510553 = 31510594
53 + 31510541 = 31510594
107 + 31510487 = 31510594
191 + 31510403 = 31510594
197 + 31510397 = 31510594
461 + 31510133 = 31510594
503 + 31510091 = 31510594
587 + 31510007 = 31510594

Showing the first eight; more decompositions exist.
