Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655218, here are decompositions:

7 + 8655211 = 8655218
181 + 8655037 = 8655218
211 + 8655007 = 8655218
277 + 8654941 = 8655218
379 + 8654839 = 8655218
409 + 8654809 = 8655218
457 + 8654761 = 8655218
577 + 8654641 = 8655218

Showing the first eight; more decompositions exist.
