Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722856, here are decompositions:

67 + 8722789 = 8722856
379 + 8722477 = 8722856
397 + 8722459 = 8722856
409 + 8722447 = 8722856
433 + 8722423 = 8722856
463 + 8722393 = 8722856
523 + 8722333 = 8722856
619 + 8722237 = 8722856

Showing the first eight; more decompositions exist.
