Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510932, here are decompositions:

23 + 31510909 = 31510932
29 + 31510903 = 31510932
31 + 31510901 = 31510932
41 + 31510891 = 31510932
151 + 31510781 = 31510932
163 + 31510769 = 31510932
179 + 31510753 = 31510932
241 + 31510691 = 31510932

Showing the first eight; more decompositions exist.
