Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657166, here are decompositions:

5 + 8657161 = 8657166
43 + 8657123 = 8657166
97 + 8657069 = 8657166
113 + 8657053 = 8657166
149 + 8657017 = 8657166
157 + 8657009 = 8657166
227 + 8656939 = 8657166
233 + 8656933 = 8657166

Showing the first eight; more decompositions exist.
