Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610468, here are decompositions:

31 + 31610437 = 31610468
79 + 31610389 = 31610468
151 + 31610317 = 31610468
181 + 31610287 = 31610468
199 + 31610269 = 31610468
271 + 31610197 = 31610468
457 + 31610011 = 31610468
607 + 31609861 = 31610468

Showing the first eight; more decompositions exist.
