Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722446, here are decompositions:

17 + 8722429 = 8722446
23 + 8722423 = 8722446
37 + 8722409 = 8722446
53 + 8722393 = 8722446
79 + 8722367 = 8722446
107 + 8722339 = 8722446
113 + 8722333 = 8722446
149 + 8722297 = 8722446

Showing the first eight; more decompositions exist.
