Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640050, here are decompositions:

37 + 8640013 = 8640050
73 + 8639977 = 8640050
127 + 8639923 = 8640050
151 + 8639899 = 8640050
241 + 8639809 = 8640050
271 + 8639779 = 8640050
277 + 8639773 = 8640050
337 + 8639713 = 8640050

Showing the first eight; more decompositions exist.
