Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728284, here are decompositions:

11 + 8728273 = 8728284
23 + 8728261 = 8728284
43 + 8728241 = 8728284
73 + 8728211 = 8728284
137 + 8728147 = 8728284
211 + 8728073 = 8728284
347 + 8727937 = 8728284
353 + 8727931 = 8728284

Showing the first eight; more decompositions exist.
