Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635668, here are decompositions:

5 + 8635663 = 8635668
11 + 8635657 = 8635668
31 + 8635637 = 8635668
37 + 8635631 = 8635668
47 + 8635621 = 8635668
61 + 8635607 = 8635668
89 + 8635579 = 8635668
101 + 8635567 = 8635668

Showing the first eight; more decompositions exist.
