Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728968, here are decompositions:

5 + 8728963 = 8728968
41 + 8728927 = 8728968
47 + 8728921 = 8728968
67 + 8728901 = 8728968
71 + 8728897 = 8728968
181 + 8728787 = 8728968
211 + 8728757 = 8728968
251 + 8728717 = 8728968

Showing the first eight; more decompositions exist.
