Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728110, here are decompositions:

31 + 8728079 = 8728110
37 + 8728073 = 8728110
73 + 8728037 = 8728110
173 + 8727937 = 8728110
179 + 8727931 = 8728110
197 + 8727913 = 8728110
211 + 8727899 = 8728110
239 + 8727871 = 8728110

Showing the first eight; more decompositions exist.
