Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510934, here are decompositions:

3 + 31510931 = 31510934
31 + 31510903 = 31510934
43 + 31510891 = 31510934
163 + 31510771 = 31510934
181 + 31510753 = 31510934
277 + 31510657 = 31510934
307 + 31510627 = 31510934
331 + 31510603 = 31510934

Showing the first eight; more decompositions exist.
