Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666016, here are decompositions:

17 + 8665999 = 8666016
43 + 8665973 = 8666016
67 + 8665949 = 8666016
83 + 8665933 = 8666016
103 + 8665913 = 8666016
127 + 8665889 = 8666016
167 + 8665849 = 8666016
199 + 8665817 = 8666016

Showing the first eight; more decompositions exist.
