Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609984, here are decompositions:

67 + 8609917 = 8609984
73 + 8609911 = 8609984
151 + 8609833 = 8609984
193 + 8609791 = 8609984
211 + 8609773 = 8609984
307 + 8609677 = 8609984
337 + 8609647 = 8609984
367 + 8609617 = 8609984

Showing the first eight; more decompositions exist.
