Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609072, here are decompositions:

163 + 8608909 = 8609072
181 + 8608891 = 8609072
193 + 8608879 = 8609072
211 + 8608861 = 8609072
271 + 8608801 = 8609072
313 + 8608759 = 8609072
463 + 8608609 = 8609072
499 + 8608573 = 8609072

Showing the first eight; more decompositions exist.
