Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663222, here are decompositions:

13 + 8663209 = 8663222
103 + 8663119 = 8663222
151 + 8663071 = 8663222
199 + 8663023 = 8663222
283 + 8662939 = 8663222
331 + 8662891 = 8663222
439 + 8662783 = 8663222
643 + 8662579 = 8663222

Showing the first eight; more decompositions exist.
