Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610464, here are decompositions:

71 + 31610393 = 31610464
101 + 31610363 = 31610464
131 + 31610333 = 31610464
173 + 31610291 = 31610464
227 + 31610237 = 31610464
233 + 31610231 = 31610464
251 + 31610213 = 31610464
293 + 31610171 = 31610464

Showing the first eight; more decompositions exist.
