Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635928, here are decompositions:

31 + 8635897 = 8635928
61 + 8635867 = 8635928
79 + 8635849 = 8635928
151 + 8635777 = 8635928
199 + 8635729 = 8635928
211 + 8635717 = 8635928
229 + 8635699 = 8635928
241 + 8635687 = 8635928

Showing the first eight; more decompositions exist.
