Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622928, here are decompositions:

5 + 8622923 = 8622928
71 + 8622857 = 8622928
317 + 8622611 = 8622928
467 + 8622461 = 8622928
569 + 8622359 = 8622928
641 + 8622287 = 8622928
719 + 8622209 = 8622928
857 + 8622071 = 8622928

Showing the first eight; more decompositions exist.
