Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628018, here are decompositions:

11 + 8628007 = 8628018
31 + 8627987 = 8628018
41 + 8627977 = 8628018
71 + 8627947 = 8628018
79 + 8627939 = 8628018
107 + 8627911 = 8628018
109 + 8627909 = 8628018
151 + 8627867 = 8628018

Showing the first eight; more decompositions exist.
