Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610260, here are decompositions:

23 + 31610237 = 31610260
29 + 31610231 = 31610260
47 + 31610213 = 31610260
89 + 31610171 = 31610260
167 + 31610093 = 31610260
179 + 31610081 = 31610260
197 + 31610063 = 31610260
251 + 31610009 = 31610260

Showing the first eight; more decompositions exist.
