Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628744, here are decompositions:

17 + 8628727 = 8628744
67 + 8628677 = 8628744
83 + 8628661 = 8628744
97 + 8628647 = 8628744
101 + 8628643 = 8628744
191 + 8628553 = 8628744
193 + 8628551 = 8628744
197 + 8628547 = 8628744

Showing the first eight; more decompositions exist.
