Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649222, here are decompositions:

11 + 8649211 = 8649222
31 + 8649191 = 8649222
151 + 8649071 = 8649222
173 + 8649049 = 8649222
193 + 8649029 = 8649222
199 + 8649023 = 8649222
269 + 8648953 = 8649222
293 + 8648929 = 8649222

Showing the first eight; more decompositions exist.
