Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628536, here are decompositions:

43 + 8628493 = 8628536
73 + 8628463 = 8628536
349 + 8628187 = 8628536
379 + 8628157 = 8628536
439 + 8628097 = 8628536
487 + 8628049 = 8628536
643 + 8627893 = 8628536
727 + 8627809 = 8628536

Showing the first eight; more decompositions exist.
