Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628908, here are decompositions:

19 + 8628889 = 8628908
61 + 8628847 = 8628908
97 + 8628811 = 8628908
109 + 8628799 = 8628908
157 + 8628751 = 8628908
181 + 8628727 = 8628908
199 + 8628709 = 8628908
307 + 8628601 = 8628908

Showing the first eight; more decompositions exist.
