Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729726, here are decompositions:

37 + 8729689 = 8729726
67 + 8729659 = 8729726
79 + 8729647 = 8729726
97 + 8729629 = 8729726
163 + 8729563 = 8729726
337 + 8729389 = 8729726
409 + 8729317 = 8729726
487 + 8729239 = 8729726

Showing the first eight; more decompositions exist.
