Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628234, here are decompositions:

31 + 8628203 = 8628234
47 + 8628187 = 8628234
53 + 8628181 = 8628234
61 + 8628173 = 8628234
73 + 8628161 = 8628234
103 + 8628131 = 8628234
113 + 8628121 = 8628234
127 + 8628107 = 8628234

Showing the first eight; more decompositions exist.
