Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668416, here are decompositions:

13 + 8668403 = 8668416
37 + 8668379 = 8668416
47 + 8668369 = 8668416
59 + 8668357 = 8668416
67 + 8668349 = 8668416
137 + 8668279 = 8668416
149 + 8668267 = 8668416
223 + 8668193 = 8668416

Showing the first eight; more decompositions exist.
