Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658222, here are decompositions:

5 + 8658217 = 8658222
19 + 8658203 = 8658222
29 + 8658193 = 8658222
61 + 8658161 = 8658222
113 + 8658109 = 8658222
163 + 8658059 = 8658222
179 + 8658043 = 8658222
239 + 8657983 = 8658222

Showing the first eight; more decompositions exist.
