Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628726, here are decompositions:

17 + 8628709 = 8628726
79 + 8628647 = 8628726
83 + 8628643 = 8628726
97 + 8628629 = 8628726
103 + 8628623 = 8628726
173 + 8628553 = 8628726
179 + 8628547 = 8628726
233 + 8628493 = 8628726

Showing the first eight; more decompositions exist.
