Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660148, here are decompositions:

41 + 8660107 = 8660148
61 + 8660087 = 8660148
67 + 8660081 = 8660148
71 + 8660077 = 8660148
97 + 8660051 = 8660148
109 + 8660039 = 8660148
149 + 8659999 = 8660148
151 + 8659997 = 8660148

Showing the first eight; more decompositions exist.
