Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722808, here are decompositions:

19 + 8722789 = 8722808
97 + 8722711 = 8722808
331 + 8722477 = 8722808
337 + 8722471 = 8722808
349 + 8722459 = 8722808
379 + 8722429 = 8722808
571 + 8722237 = 8722808
691 + 8722117 = 8722808

Showing the first eight; more decompositions exist.
