Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510366, here are decompositions:

3 + 31510363 = 31510366
47 + 31510319 = 31510366
149 + 31510217 = 31510366
179 + 31510187 = 31510366
197 + 31510169 = 31510366
227 + 31510139 = 31510366
233 + 31510133 = 31510366
359 + 31510007 = 31510366

Showing the first eight; more decompositions exist.
