Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610262, here are decompositions:

31 + 31610231 = 31610262
149 + 31610113 = 31610262
179 + 31610083 = 31610262
181 + 31610081 = 31610262
199 + 31610063 = 31610262
223 + 31610039 = 31610262
239 + 31610023 = 31610262
251 + 31610011 = 31610262

Showing the first eight; more decompositions exist.
