Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610382, here are decompositions:

19 + 31610363 = 31610382
29 + 31610353 = 31610382
43 + 31610339 = 31610382
103 + 31610279 = 31610382
113 + 31610269 = 31610382
151 + 31610231 = 31610382
211 + 31610171 = 31610382
239 + 31610143 = 31610382

Showing the first eight; more decompositions exist.
