Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628240, here are decompositions:

7 + 8628233 = 8628240
37 + 8628203 = 8628240
53 + 8628187 = 8628240
59 + 8628181 = 8628240
67 + 8628173 = 8628240
79 + 8628161 = 8628240
83 + 8628157 = 8628240
109 + 8628131 = 8628240

Showing the first eight; more decompositions exist.
