Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644376, here are decompositions:

163 + 8644213 = 8644376
229 + 8644147 = 8644376
379 + 8643997 = 8644376
457 + 8643919 = 8644376
487 + 8643889 = 8644376
619 + 8643757 = 8644376
757 + 8643619 = 8644376
787 + 8643589 = 8644376

Showing the first eight; more decompositions exist.
