Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668436, here are decompositions:

13 + 8668423 = 8668436
67 + 8668369 = 8668436
79 + 8668357 = 8668436
157 + 8668279 = 8668436
163 + 8668273 = 8668436
229 + 8668207 = 8668436
373 + 8668063 = 8668436
379 + 8668057 = 8668436

Showing the first eight; more decompositions exist.
