Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728516, here are decompositions:

3 + 8728513 = 8728516
59 + 8728457 = 8728516
89 + 8728427 = 8728516
227 + 8728289 = 8728516
347 + 8728169 = 8728516
443 + 8728073 = 8728516
479 + 8728037 = 8728516
617 + 8727899 = 8728516

Showing the first eight; more decompositions exist.
