Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722898, here are decompositions:

7 + 8722891 = 8722898
109 + 8722789 = 8722898
277 + 8722621 = 8722898
421 + 8722477 = 8722898
439 + 8722459 = 8722898
601 + 8722297 = 8722898
607 + 8722291 = 8722898
661 + 8722237 = 8722898

Showing the first eight; more decompositions exist.
