Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722494, here are decompositions:

17 + 8722477 = 8722494
23 + 8722471 = 8722494
47 + 8722447 = 8722494
71 + 8722423 = 8722494
101 + 8722393 = 8722494
103 + 8722391 = 8722494
127 + 8722367 = 8722494
163 + 8722331 = 8722494

Showing the first eight; more decompositions exist.
