Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635620, here are decompositions:

13 + 8635607 = 8635620
41 + 8635579 = 8635620
53 + 8635567 = 8635620
61 + 8635559 = 8635620
67 + 8635553 = 8635620
89 + 8635531 = 8635620
107 + 8635513 = 8635620
151 + 8635469 = 8635620

Showing the first eight; more decompositions exist.
