Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628946, here are decompositions:

23 + 8628923 = 8628946
47 + 8628899 = 8628946
89 + 8628857 = 8628946
167 + 8628779 = 8628946
173 + 8628773 = 8628946
269 + 8628677 = 8628946
317 + 8628629 = 8628946
467 + 8628479 = 8628946

Showing the first eight; more decompositions exist.
