Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706660, here are decompositions:

13 + 8706647 = 8706660
47 + 8706613 = 8706660
73 + 8706587 = 8706660
103 + 8706557 = 8706660
107 + 8706553 = 8706660
113 + 8706547 = 8706660
163 + 8706497 = 8706660
181 + 8706479 = 8706660

Showing the first eight; more decompositions exist.
