Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610470, here are decompositions:

107 + 31610363 = 31610470
131 + 31610339 = 31610470
137 + 31610333 = 31610470
179 + 31610291 = 31610470
191 + 31610279 = 31610470
233 + 31610237 = 31610470
239 + 31610231 = 31610470
257 + 31610213 = 31610470

Showing the first eight; more decompositions exist.
