Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616660, here are decompositions:

7 + 8616653 = 8616660
61 + 8616599 = 8616660
97 + 8616563 = 8616660
113 + 8616547 = 8616660
127 + 8616533 = 8616660
167 + 8616493 = 8616660
229 + 8616431 = 8616660
263 + 8616397 = 8616660

Showing the first eight; more decompositions exist.
