Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628786, here are decompositions:

7 + 8628779 = 8628786
13 + 8628773 = 8628786
59 + 8628727 = 8628786
109 + 8628677 = 8628786
139 + 8628647 = 8628786
157 + 8628629 = 8628786
163 + 8628623 = 8628786
233 + 8628553 = 8628786

Showing the first eight; more decompositions exist.
