Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639222, here are decompositions:

3 + 8639219 = 8639222
61 + 8639161 = 8639222
73 + 8639149 = 8639222
79 + 8639143 = 8639222
103 + 8639119 = 8639222
211 + 8639011 = 8639222
223 + 8638999 = 8639222
271 + 8638951 = 8639222

Showing the first eight; more decompositions exist.
