Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638922, here are decompositions:

13 + 8638909 = 8638922
31 + 8638891 = 8638922
73 + 8638849 = 8638922
79 + 8638843 = 8638922
379 + 8638543 = 8638922
541 + 8638381 = 8638922
631 + 8638291 = 8638922
709 + 8638213 = 8638922

Showing the first eight; more decompositions exist.
