Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668122, here are decompositions:

11 + 8668111 = 8668122
41 + 8668081 = 8668122
59 + 8668063 = 8668122
61 + 8668061 = 8668122
79 + 8668043 = 8668122
149 + 8667973 = 8668122
173 + 8667949 = 8668122
191 + 8667931 = 8668122

Showing the first eight; more decompositions exist.
