Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728836, here are decompositions:

13 + 8728823 = 8728836
29 + 8728807 = 8728836
79 + 8728757 = 8728836
157 + 8728679 = 8728836
173 + 8728663 = 8728836
227 + 8728609 = 8728836
229 + 8728607 = 8728836
239 + 8728597 = 8728836

Showing the first eight; more decompositions exist.
