Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511054, here are decompositions:

13 + 31511041 = 31511054
61 + 31510993 = 31511054
97 + 31510957 = 31511054
151 + 31510903 = 31511054
163 + 31510891 = 31511054
241 + 31510813 = 31511054
283 + 31510771 = 31511054
373 + 31510681 = 31511054

Showing the first eight; more decompositions exist.
