Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610, here are decompositions:

3 + 31607 = 31610
37 + 31573 = 31610
43 + 31567 = 31610
67 + 31543 = 31610
79 + 31531 = 31610
97 + 31513 = 31610
223 + 31387 = 31610
277 + 31333 = 31610

Showing the first eight; more decompositions exist.
