Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628108, here are decompositions:

11 + 8628097 = 8628108
31 + 8628077 = 8628108
59 + 8628049 = 8628108
89 + 8628019 = 8628108
101 + 8628007 = 8628108
131 + 8627977 = 8628108
197 + 8627911 = 8628108
199 + 8627909 = 8628108

Showing the first eight; more decompositions exist.
