Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649946, here are decompositions:

17 + 8649929 = 8649946
59 + 8649887 = 8649946
89 + 8649857 = 8649946
257 + 8649689 = 8649946
269 + 8649677 = 8649946
317 + 8649629 = 8649946
467 + 8649479 = 8649946
479 + 8649467 = 8649946

Showing the first eight; more decompositions exist.
