Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644766, here are decompositions:

37 + 8644729 = 8644766
43 + 8644723 = 8644766
157 + 8644609 = 8644766
313 + 8644453 = 8644766
439 + 8644327 = 8644766
523 + 8644243 = 8644766
619 + 8644147 = 8644766
643 + 8644123 = 8644766

Showing the first eight; more decompositions exist.
