Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639166, here are decompositions:

5 + 8639161 = 8639166
13 + 8639153 = 8639166
17 + 8639149 = 8639166
23 + 8639143 = 8639166
43 + 8639123 = 8639166
47 + 8639119 = 8639166
59 + 8639107 = 8639166
103 + 8639063 = 8639166

Showing the first eight; more decompositions exist.
