Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635940, here are decompositions:

7 + 8635933 = 8635940
13 + 8635927 = 8635940
43 + 8635897 = 8635940
73 + 8635867 = 8635940
163 + 8635777 = 8635940
211 + 8635729 = 8635940
223 + 8635717 = 8635940
241 + 8635699 = 8635940

Showing the first eight; more decompositions exist.
