Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622228, here are decompositions:

5 + 8622223 = 8622228
19 + 8622209 = 8622228
37 + 8622191 = 8622228
101 + 8622127 = 8622228
157 + 8622071 = 8622228
211 + 8622017 = 8622228
227 + 8622001 = 8622228
239 + 8621989 = 8622228

Showing the first eight; more decompositions exist.
