Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660166, here are decompositions:

5 + 8660161 = 8660166
59 + 8660107 = 8660166
79 + 8660087 = 8660166
89 + 8660077 = 8660166
113 + 8660053 = 8660166
127 + 8660039 = 8660166
167 + 8659999 = 8660166
227 + 8659939 = 8660166

Showing the first eight; more decompositions exist.
