Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621676, here are decompositions:

3 + 31621673 = 31621676
7 + 31621669 = 31621676
43 + 31621633 = 31621676
199 + 31621477 = 31621676
277 + 31621399 = 31621676
283 + 31621393 = 31621676
409 + 31621267 = 31621676
439 + 31621237 = 31621676

Showing the first eight; more decompositions exist.
