Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658166, here are decompositions:

5 + 8658161 = 8658166
29 + 8658137 = 8658166
59 + 8658107 = 8658166
107 + 8658059 = 8658166
149 + 8658017 = 8658166
197 + 8657969 = 8658166
233 + 8657933 = 8658166
239 + 8657927 = 8658166

Showing the first eight; more decompositions exist.
