Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644586, here are decompositions:

79 + 8644507 = 8644586
109 + 8644477 = 8644586
373 + 8644213 = 8644586
439 + 8644147 = 8644586
463 + 8644123 = 8644586
829 + 8643757 = 8644586
967 + 8643619 = 8644586
997 + 8643589 = 8644586

Showing the first eight; more decompositions exist.
