Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628168, here are decompositions:

7 + 8628161 = 8628168
11 + 8628157 = 8628168
19 + 8628149 = 8628168
37 + 8628131 = 8628168
47 + 8628121 = 8628168
61 + 8628107 = 8628168
71 + 8628097 = 8628168
137 + 8628031 = 8628168

Showing the first eight; more decompositions exist.
