Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722864, here are decompositions:

5 + 8722859 = 8722864
23 + 8722841 = 8722864
107 + 8722757 = 8722864
191 + 8722673 = 8722864
233 + 8722631 = 8722864
251 + 8722613 = 8722864
257 + 8722607 = 8722864
347 + 8722517 = 8722864

Showing the first eight; more decompositions exist.
