Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622508, here are decompositions:

17 + 8622491 = 8622508
47 + 8622461 = 8622508
149 + 8622359 = 8622508
317 + 8622191 = 8622508
467 + 8622041 = 8622508
491 + 8622017 = 8622508
569 + 8621939 = 8622508
641 + 8621867 = 8622508

Showing the first eight; more decompositions exist.
