Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640086, here are decompositions:

73 + 8640013 = 8640086
109 + 8639977 = 8640086
163 + 8639923 = 8640086
223 + 8639863 = 8640086
277 + 8639809 = 8640086
283 + 8639803 = 8640086
307 + 8639779 = 8640086
313 + 8639773 = 8640086

Showing the first eight; more decompositions exist.
