Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660112, here are decompositions:

5 + 8660107 = 8660112
31 + 8660081 = 8660112
59 + 8660053 = 8660112
61 + 8660051 = 8660112
73 + 8660039 = 8660112
79 + 8660033 = 8660112
113 + 8659999 = 8660112
163 + 8659949 = 8660112

Showing the first eight; more decompositions exist.
