Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610358, here are decompositions:

5 + 31610353 = 31610358
19 + 31610339 = 31610358
41 + 31610317 = 31610358
67 + 31610291 = 31610358
71 + 31610287 = 31610358
79 + 31610279 = 31610358
89 + 31610269 = 31610358
127 + 31610231 = 31610358

Showing the first eight; more decompositions exist.
