Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628216, here are decompositions:

13 + 8628203 = 8628216
29 + 8628187 = 8628216
43 + 8628173 = 8628216
59 + 8628157 = 8628216
67 + 8628149 = 8628216
109 + 8628107 = 8628216
139 + 8628077 = 8628216
167 + 8628049 = 8628216

Showing the first eight; more decompositions exist.
