Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705724, here are decompositions:

43 + 8705681 = 8705724
67 + 8705657 = 8705724
107 + 8705617 = 8705724
113 + 8705611 = 8705724
151 + 8705573 = 8705724
163 + 8705561 = 8705724
173 + 8705551 = 8705724
193 + 8705531 = 8705724

Showing the first eight; more decompositions exist.
