Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621460, here are decompositions:

7 + 8621453 = 8621460
17 + 8621443 = 8621460
31 + 8621429 = 8621460
47 + 8621413 = 8621460
83 + 8621377 = 8621460
151 + 8621309 = 8621460
179 + 8621281 = 8621460
223 + 8621237 = 8621460

Showing the first eight; more decompositions exist.
