Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669188, here are decompositions:

29 + 8669159 = 8669188
71 + 8669117 = 8669188
389 + 8668799 = 8669188
449 + 8668739 = 8669188
467 + 8668721 = 8669188
491 + 8668697 = 8669188
617 + 8668571 = 8669188
641 + 8668547 = 8669188

Showing the first eight; more decompositions exist.
