Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609166, here are decompositions:

17 + 8609149 = 8609166
29 + 8609137 = 8609166
37 + 8609129 = 8609166
47 + 8609119 = 8609166
67 + 8609099 = 8609166
73 + 8609093 = 8609166
79 + 8609087 = 8609166
89 + 8609077 = 8609166

Showing the first eight; more decompositions exist.
