Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610392, here are decompositions:

3 + 31610389 = 31610392
29 + 31610363 = 31610392
53 + 31610339 = 31610392
59 + 31610333 = 31610392
101 + 31610291 = 31610392
113 + 31610279 = 31610392
179 + 31610213 = 31610392
251 + 31610141 = 31610392

Showing the first eight; more decompositions exist.
