Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643422, here are decompositions:

13 + 8643409 = 8643422
79 + 8643343 = 8643422
199 + 8643223 = 8643422
211 + 8643211 = 8643422
223 + 8643199 = 8643422
241 + 8643181 = 8643422
313 + 8643109 = 8643422
331 + 8643091 = 8643422

Showing the first eight; more decompositions exist.
