Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666022, here are decompositions:

5 + 8666017 = 8666022
23 + 8665999 = 8666022
31 + 8665991 = 8666022
73 + 8665949 = 8666022
83 + 8665939 = 8666022
89 + 8665933 = 8666022
109 + 8665913 = 8666022
149 + 8665873 = 8666022

Showing the first eight; more decompositions exist.
