Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610344, here are decompositions:

5 + 31610339 = 31610344
11 + 31610333 = 31610344
53 + 31610291 = 31610344
107 + 31610237 = 31610344
113 + 31610231 = 31610344
131 + 31610213 = 31610344
173 + 31610171 = 31610344
251 + 31610093 = 31610344

Showing the first eight; more decompositions exist.
