Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628166, here are decompositions:

5 + 8628161 = 8628166
17 + 8628149 = 8628166
59 + 8628107 = 8628166
89 + 8628077 = 8628166
149 + 8628017 = 8628166
179 + 8627987 = 8628166
227 + 8627939 = 8628166
257 + 8627909 = 8628166

Showing the first eight; more decompositions exist.
