Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610298, here are decompositions:

7 + 31610291 = 31610298
11 + 31610287 = 31610298
19 + 31610279 = 31610298
29 + 31610269 = 31610298
61 + 31610237 = 31610298
67 + 31610231 = 31610298
101 + 31610197 = 31610298
127 + 31610171 = 31610298

Showing the first eight; more decompositions exist.
