Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635660, here are decompositions:

3 + 8635657 = 8635660
23 + 8635637 = 8635660
29 + 8635631 = 8635660
53 + 8635607 = 8635660
101 + 8635559 = 8635660
107 + 8635553 = 8635660
191 + 8635469 = 8635660
227 + 8635433 = 8635660

Showing the first eight; more decompositions exist.
