Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610338, here are decompositions:

5 + 31610333 = 31610338
47 + 31610291 = 31610338
59 + 31610279 = 31610338
101 + 31610237 = 31610338
107 + 31610231 = 31610338
167 + 31610171 = 31610338
197 + 31610141 = 31610338
257 + 31610081 = 31610338

Showing the first eight; more decompositions exist.
