Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621676, here are decompositions:

23 + 8621653 = 8621676
53 + 8621623 = 8621676
59 + 8621617 = 8621676
67 + 8621609 = 8621676
197 + 8621479 = 8621676
199 + 8621477 = 8621676
223 + 8621453 = 8621676
233 + 8621443 = 8621676

Showing the first eight; more decompositions exist.
