Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628836, here are decompositions:

37 + 8628799 = 8628836
109 + 8628727 = 8628836
127 + 8628709 = 8628836
193 + 8628643 = 8628836
283 + 8628553 = 8628836
373 + 8628463 = 8628836
487 + 8628349 = 8628836
739 + 8628097 = 8628836

Showing the first eight; more decompositions exist.
