Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686166, here are decompositions:

3 + 8686163 = 8686166
7 + 8686159 = 8686166
19 + 8686147 = 8686166
43 + 8686123 = 8686166
79 + 8686087 = 8686166
163 + 8686003 = 8686166
199 + 8685967 = 8686166
397 + 8685769 = 8686166

Showing the first eight; more decompositions exist.
