Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660130, here are decompositions:

23 + 8660107 = 8660130
43 + 8660087 = 8660130
53 + 8660077 = 8660130
79 + 8660051 = 8660130
97 + 8660033 = 8660130
131 + 8659999 = 8660130
173 + 8659957 = 8660130
181 + 8659949 = 8660130

Showing the first eight; more decompositions exist.
