Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722958, here are decompositions:

67 + 8722891 = 8722958
337 + 8722621 = 8722958
487 + 8722471 = 8722958
499 + 8722459 = 8722958
619 + 8722339 = 8722958
661 + 8722297 = 8722958
787 + 8722171 = 8722958
859 + 8722099 = 8722958

Showing the first eight; more decompositions exist.
