Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628938, here are decompositions:

79 + 8628859 = 8628938
127 + 8628811 = 8628938
139 + 8628799 = 8628938
151 + 8628787 = 8628938
211 + 8628727 = 8628938
229 + 8628709 = 8628938
277 + 8628661 = 8628938
337 + 8628601 = 8628938

Showing the first eight; more decompositions exist.
