Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728086, here are decompositions:

7 + 8728079 = 8728086
13 + 8728073 = 8728086
97 + 8727989 = 8728086
149 + 8727937 = 8728086
173 + 8727913 = 8728086
179 + 8727907 = 8728086
229 + 8727857 = 8728086
277 + 8727809 = 8728086

Showing the first eight; more decompositions exist.
