Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668222, here are decompositions:

29 + 8668193 = 8668222
71 + 8668151 = 8668222
89 + 8668133 = 8668222
149 + 8668073 = 8668222
179 + 8668043 = 8668222
191 + 8668031 = 8668222
293 + 8667929 = 8668222
359 + 8667863 = 8668222

Showing the first eight; more decompositions exist.
