Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661166, here are decompositions:

5 + 8661161 = 8661166
29 + 8661137 = 8661166
47 + 8661119 = 8661166
179 + 8660987 = 8661166
197 + 8660969 = 8661166
233 + 8660933 = 8661166
257 + 8660909 = 8661166
347 + 8660819 = 8661166

Showing the first eight; more decompositions exist.
