Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722894, here are decompositions:

3 + 8722891 = 8722894
17 + 8722877 = 8722894
53 + 8722841 = 8722894
137 + 8722757 = 8722894
233 + 8722661 = 8722894
251 + 8722643 = 8722894
263 + 8722631 = 8722894
281 + 8722613 = 8722894

Showing the first eight; more decompositions exist.
