Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668636, here are decompositions:

23 + 8668613 = 8668636
59 + 8668577 = 8668636
83 + 8668553 = 8668636
89 + 8668547 = 8668636
113 + 8668523 = 8668636
233 + 8668403 = 8668636
257 + 8668379 = 8668636
269 + 8668367 = 8668636

Showing the first eight; more decompositions exist.
