Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668736, here are decompositions:

127 + 8668609 = 8668736
277 + 8668459 = 8668736
313 + 8668423 = 8668736
367 + 8668369 = 8668736
379 + 8668357 = 8668736
457 + 8668279 = 8668736
463 + 8668273 = 8668736
673 + 8668063 = 8668736

Showing the first eight; more decompositions exist.
