Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728176, here are decompositions:

7 + 8728169 = 8728176
29 + 8728147 = 8728176
47 + 8728129 = 8728176
97 + 8728079 = 8728176
103 + 8728073 = 8728176
139 + 8728037 = 8728176
239 + 8727937 = 8728176
263 + 8727913 = 8728176

Showing the first eight; more decompositions exist.
