Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729810, here are decompositions:

43 + 8729767 = 8729810
151 + 8729659 = 8729810
163 + 8729647 = 8729810
181 + 8729629 = 8729810
409 + 8729401 = 8729810
421 + 8729389 = 8729810
487 + 8729323 = 8729810
571 + 8729239 = 8729810

Showing the first eight; more decompositions exist.
