Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683660, here are decompositions:

3 + 8683657 = 8683660
23 + 8683637 = 8683660
47 + 8683613 = 8683660
53 + 8683607 = 8683660
107 + 8683553 = 8683660
131 + 8683529 = 8683660
137 + 8683523 = 8683660
149 + 8683511 = 8683660

Showing the first eight; more decompositions exist.
