Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511096, here are decompositions:

7 + 31511089 = 31511096
103 + 31510993 = 31511096
139 + 31510957 = 31511096
163 + 31510933 = 31511096
193 + 31510903 = 31511096
283 + 31510813 = 31511096
307 + 31510789 = 31511096
439 + 31510657 = 31511096

Showing the first eight; more decompositions exist.
