Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722776, here are decompositions:

19 + 8722757 = 8722776
37 + 8722739 = 8722776
103 + 8722673 = 8722776
163 + 8722613 = 8722776
173 + 8722603 = 8722776
277 + 8722499 = 8722776
317 + 8722459 = 8722776
347 + 8722429 = 8722776

Showing the first eight; more decompositions exist.
