Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510024, here are decompositions:

3 + 31510021 = 31510024
17 + 31510007 = 31510024
23 + 31510001 = 31510024
53 + 31509971 = 31510024
83 + 31509941 = 31510024
131 + 31509893 = 31510024
173 + 31509851 = 31510024
233 + 31509791 = 31510024

Showing the first eight; more decompositions exist.
