Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609786, here are decompositions:

13 + 8609773 = 8609786
67 + 8609719 = 8609786
103 + 8609683 = 8609786
109 + 8609677 = 8609786
139 + 8609647 = 8609786
223 + 8609563 = 8609786
313 + 8609473 = 8609786
337 + 8609449 = 8609786

Showing the first eight; more decompositions exist.
