Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646422, here are decompositions:

19 + 8646403 = 8646422
61 + 8646361 = 8646422
163 + 8646259 = 8646422
199 + 8646223 = 8646422
241 + 8646181 = 8646422
523 + 8645899 = 8646422
619 + 8645803 = 8646422
661 + 8645761 = 8646422

Showing the first eight; more decompositions exist.
