Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729700, here are decompositions:

11 + 8729689 = 8729700
19 + 8729681 = 8729700
41 + 8729659 = 8729700
53 + 8729647 = 8729700
59 + 8729641 = 8729700
71 + 8729629 = 8729700
79 + 8729621 = 8729700
97 + 8729603 = 8729700

Showing the first eight; more decompositions exist.
