Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646166, here are decompositions:

3 + 8646163 = 8646166
47 + 8646119 = 8646166
59 + 8646107 = 8646166
107 + 8646059 = 8646166
149 + 8646017 = 8646166
239 + 8645927 = 8646166
317 + 8645849 = 8646166
479 + 8645687 = 8646166

Showing the first eight; more decompositions exist.
