Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660178, here are decompositions:

17 + 8660161 = 8660178
71 + 8660107 = 8660178
97 + 8660081 = 8660178
101 + 8660077 = 8660178
127 + 8660051 = 8660178
139 + 8660039 = 8660178
179 + 8659999 = 8660178
181 + 8659997 = 8660178

Showing the first eight; more decompositions exist.
