Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622216, here are decompositions:

7 + 8622209 = 8622216
79 + 8622137 = 8622216
89 + 8622127 = 8622216
103 + 8622113 = 8622216
193 + 8622023 = 8622216
199 + 8622017 = 8622216
227 + 8621989 = 8622216
233 + 8621983 = 8622216

Showing the first eight; more decompositions exist.
