Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609216, here are decompositions:

43 + 8609173 = 8609216
67 + 8609149 = 8609216
79 + 8609137 = 8609216
97 + 8609119 = 8609216
139 + 8609077 = 8609216
193 + 8609023 = 8609216
307 + 8608909 = 8609216
337 + 8608879 = 8609216

Showing the first eight; more decompositions exist.
