Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628886, here are decompositions:

3 + 8628883 = 8628886
29 + 8628857 = 8628886
107 + 8628779 = 8628886
113 + 8628773 = 8628886
239 + 8628647 = 8628886
257 + 8628629 = 8628886
263 + 8628623 = 8628886
443 + 8628443 = 8628886

Showing the first eight; more decompositions exist.
