Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728600, here are decompositions:

3 + 8728597 = 8728600
29 + 8728571 = 8728600
173 + 8728427 = 8728600
227 + 8728373 = 8728600
269 + 8728331 = 8728600
311 + 8728289 = 8728600
359 + 8728241 = 8728600
389 + 8728211 = 8728600

Showing the first eight; more decompositions exist.
