Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728300, here are decompositions:

11 + 8728289 = 8728300
59 + 8728241 = 8728300
89 + 8728211 = 8728300
107 + 8728193 = 8728300
131 + 8728169 = 8728300
227 + 8728073 = 8728300
263 + 8728037 = 8728300
311 + 8727989 = 8728300

Showing the first eight; more decompositions exist.
