Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722926, here are decompositions:

13 + 8722913 = 8722926
67 + 8722859 = 8722926
97 + 8722829 = 8722926
127 + 8722799 = 8722926
137 + 8722789 = 8722926
283 + 8722643 = 8722926
313 + 8722613 = 8722926
409 + 8722517 = 8722926

Showing the first eight; more decompositions exist.
