Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628506, here are decompositions:

13 + 8628493 = 8628506
43 + 8628463 = 8628506
157 + 8628349 = 8628506
349 + 8628157 = 8628506
409 + 8628097 = 8628506
457 + 8628049 = 8628506
487 + 8628019 = 8628506
499 + 8628007 = 8628506

Showing the first eight; more decompositions exist.
