Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728804, here are decompositions:

17 + 8728787 = 8728804
47 + 8728757 = 8728804
83 + 8728721 = 8728804
113 + 8728691 = 8728804
197 + 8728607 = 8728804
233 + 8728571 = 8728804
347 + 8728457 = 8728804
431 + 8728373 = 8728804

Showing the first eight; more decompositions exist.
