Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728826, here are decompositions:

3 + 8728823 = 8728826
19 + 8728807 = 8728826
109 + 8728717 = 8728826
163 + 8728663 = 8728826
199 + 8728627 = 8728826
229 + 8728597 = 8728826
277 + 8728549 = 8728826
313 + 8728513 = 8728826

Showing the first eight; more decompositions exist.
