Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640036, here are decompositions:

19 + 8640017 = 8640036
23 + 8640013 = 8640036
59 + 8639977 = 8640036
113 + 8639923 = 8640036
127 + 8639909 = 8640036
137 + 8639899 = 8640036
173 + 8639863 = 8640036
199 + 8639837 = 8640036

Showing the first eight; more decompositions exist.
