Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510360, here are decompositions:

41 + 31510319 = 31510360
137 + 31510223 = 31510360
173 + 31510187 = 31510360
191 + 31510169 = 31510360
227 + 31510133 = 31510360
239 + 31510121 = 31510360
269 + 31510091 = 31510360
281 + 31510079 = 31510360

Showing the first eight; more decompositions exist.
