Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511058, here are decompositions:

17 + 31511041 = 31511058
101 + 31510957 = 31511058
127 + 31510931 = 31511058
149 + 31510909 = 31511058
157 + 31510901 = 31511058
167 + 31510891 = 31511058
211 + 31510847 = 31511058
269 + 31510789 = 31511058

Showing the first eight; more decompositions exist.
