Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511060, here are decompositions:

3 + 31511057 = 31511060
19 + 31511041 = 31511060
67 + 31510993 = 31511060
103 + 31510957 = 31511060
127 + 31510933 = 31511060
151 + 31510909 = 31511060
157 + 31510903 = 31511060
271 + 31510789 = 31511060

Showing the first eight; more decompositions exist.
