Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666214, here are decompositions:

13 + 8666201 = 8666214
31 + 8666183 = 8666214
41 + 8666173 = 8666214
47 + 8666167 = 8666214
61 + 8666153 = 8666214
157 + 8666057 = 8666214
163 + 8666051 = 8666214
191 + 8666023 = 8666214

Showing the first eight; more decompositions exist.
