Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635980, here are decompositions:

11 + 8635969 = 8635980
13 + 8635967 = 8635980
29 + 8635951 = 8635980
47 + 8635933 = 8635980
53 + 8635927 = 8635980
61 + 8635919 = 8635980
83 + 8635897 = 8635980
97 + 8635883 = 8635980

Showing the first eight; more decompositions exist.
