Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628008, here are decompositions:

31 + 8627977 = 8628008
61 + 8627947 = 8628008
97 + 8627911 = 8628008
157 + 8627851 = 8628008
199 + 8627809 = 8628008
307 + 8627701 = 8628008
397 + 8627611 = 8628008
439 + 8627569 = 8628008

Showing the first eight; more decompositions exist.
