Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729764, here are decompositions:

47 + 8729717 = 8729764
53 + 8729711 = 8729764
83 + 8729681 = 8729764
353 + 8729411 = 8729764
431 + 8729333 = 8729764
521 + 8729243 = 8729764
557 + 8729207 = 8729764
647 + 8729117 = 8729764

Showing the first eight; more decompositions exist.
