Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728104, here are decompositions:

31 + 8728073 = 8728104
67 + 8728037 = 8728104
167 + 8727937 = 8728104
173 + 8727931 = 8728104
191 + 8727913 = 8728104
197 + 8727907 = 8728104
233 + 8727871 = 8728104
313 + 8727791 = 8728104

Showing the first eight; more decompositions exist.
