Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610188, here are decompositions:

17 + 31610171 = 31610188
47 + 31610141 = 31610188
107 + 31610081 = 31610188
149 + 31610039 = 31610188
179 + 31610009 = 31610188
251 + 31609937 = 31610188
257 + 31609931 = 31610188
317 + 31609871 = 31610188

Showing the first eight; more decompositions exist.
