Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649422, here are decompositions:

3 + 8649419 = 8649422
13 + 8649409 = 8649422
31 + 8649391 = 8649422
73 + 8649349 = 8649422
79 + 8649343 = 8649422
139 + 8649283 = 8649422
181 + 8649241 = 8649422
211 + 8649211 = 8649422

Showing the first eight; more decompositions exist.
