Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728266, here are decompositions:

5 + 8728261 = 8728266
59 + 8728207 = 8728266
73 + 8728193 = 8728266
97 + 8728169 = 8728266
137 + 8728129 = 8728266
193 + 8728073 = 8728266
229 + 8728037 = 8728266
277 + 8727989 = 8728266

Showing the first eight; more decompositions exist.
