Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668536, here are decompositions:

13 + 8668523 = 8668536
17 + 8668519 = 8668536
47 + 8668489 = 8668536
53 + 8668483 = 8668536
113 + 8668423 = 8668536
157 + 8668379 = 8668536
167 + 8668369 = 8668536
179 + 8668357 = 8668536

Showing the first eight; more decompositions exist.
