Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666208, here are decompositions:

7 + 8666201 = 8666208
41 + 8666167 = 8666208
71 + 8666137 = 8666208
139 + 8666069 = 8666208
149 + 8666059 = 8666208
151 + 8666057 = 8666208
157 + 8666051 = 8666208
181 + 8666027 = 8666208

Showing the first eight; more decompositions exist.
