Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621836, here are decompositions:

5 + 8621831 = 8621836
17 + 8621819 = 8621836
89 + 8621747 = 8621836
227 + 8621609 = 8621836
359 + 8621477 = 8621836
383 + 8621453 = 8621836
593 + 8621243 = 8621836
599 + 8621237 = 8621836

Showing the first eight; more decompositions exist.
