Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622222, here are decompositions:

13 + 8622209 = 8622222
31 + 8622191 = 8622222
109 + 8622113 = 8622222
151 + 8622071 = 8622222
181 + 8622041 = 8622222
199 + 8622023 = 8622222
211 + 8622011 = 8622222
233 + 8621989 = 8622222

Showing the first eight; more decompositions exist.
