Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511094, here are decompositions:

5 + 31511089 = 31511094
23 + 31511071 = 31511094
37 + 31511057 = 31511094
53 + 31511041 = 31511094
101 + 31510993 = 31511094
137 + 31510957 = 31511094
163 + 31510931 = 31511094
191 + 31510903 = 31511094

Showing the first eight; more decompositions exist.
