Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728306, here are decompositions:

3 + 8728303 = 8728306
17 + 8728289 = 8728306
113 + 8728193 = 8728306
137 + 8728169 = 8728306
227 + 8728079 = 8728306
233 + 8728073 = 8728306
269 + 8728037 = 8728306
317 + 8727989 = 8728306

Showing the first eight; more decompositions exist.
