Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511074, here are decompositions:

3 + 31511071 = 31511074
5 + 31511069 = 31511074
17 + 31511057 = 31511074
71 + 31511003 = 31511074
173 + 31510901 = 31511074
227 + 31510847 = 31511074
263 + 31510811 = 31511074
293 + 31510781 = 31511074

Showing the first eight; more decompositions exist.
