Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729706, here are decompositions:

17 + 8729689 = 8729706
47 + 8729659 = 8729706
59 + 8729647 = 8729706
103 + 8729603 = 8729706
113 + 8729593 = 8729706
149 + 8729557 = 8729706
163 + 8729543 = 8729706
239 + 8729467 = 8729706

Showing the first eight; more decompositions exist.
