Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621822, here are decompositions:

3 + 8621819 = 8621822
43 + 8621779 = 8621822
73 + 8621749 = 8621822
199 + 8621623 = 8621822
241 + 8621581 = 8621822
271 + 8621551 = 8621822
331 + 8621491 = 8621822
379 + 8621443 = 8621822

Showing the first eight; more decompositions exist.
