Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510962, here are decompositions:

5 + 31510957 = 31510962
29 + 31510933 = 31510962
31 + 31510931 = 31510962
53 + 31510909 = 31510962
59 + 31510903 = 31510962
61 + 31510901 = 31510962
71 + 31510891 = 31510962
149 + 31510813 = 31510962

Showing the first eight; more decompositions exist.
