Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628746, here are decompositions:

19 + 8628727 = 8628746
37 + 8628709 = 8628746
103 + 8628643 = 8628746
193 + 8628553 = 8628746
199 + 8628547 = 8628746
283 + 8628463 = 8628746
397 + 8628349 = 8628746
727 + 8628019 = 8628746

Showing the first eight; more decompositions exist.
