Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621480, here are decompositions:

3 + 8621477 = 8621480
13 + 8621467 = 8621480
37 + 8621443 = 8621480
67 + 8621413 = 8621480
103 + 8621377 = 8621480
181 + 8621299 = 8621480
199 + 8621281 = 8621480
271 + 8621209 = 8621480

Showing the first eight; more decompositions exist.
