Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645166, here are decompositions:

43 + 8645123 = 8645166
53 + 8645113 = 8645166
113 + 8645053 = 8645166
137 + 8645029 = 8645166
157 + 8645009 = 8645166
239 + 8644927 = 8645166
263 + 8644903 = 8645166
293 + 8644873 = 8645166

Showing the first eight; more decompositions exist.
