Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728252, here are decompositions:

11 + 8728241 = 8728252
41 + 8728211 = 8728252
59 + 8728193 = 8728252
83 + 8728169 = 8728252
173 + 8728079 = 8728252
179 + 8728073 = 8728252
263 + 8727989 = 8728252
353 + 8727899 = 8728252

Showing the first eight; more decompositions exist.
