Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728134, here are decompositions:

5 + 8728129 = 8728134
61 + 8728073 = 8728134
97 + 8728037 = 8728134
197 + 8727937 = 8728134
227 + 8727907 = 8728134
263 + 8727871 = 8728134
277 + 8727857 = 8728134
367 + 8727767 = 8728134

Showing the first eight; more decompositions exist.
