Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729756, here are decompositions:

67 + 8729689 = 8729756
97 + 8729659 = 8729756
109 + 8729647 = 8729756
127 + 8729629 = 8729756
163 + 8729593 = 8729756
193 + 8729563 = 8729756
199 + 8729557 = 8729756
367 + 8729389 = 8729756

Showing the first eight; more decompositions exist.
