Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609840, here are decompositions:

7 + 8609833 = 8609840
67 + 8609773 = 8609840
157 + 8609683 = 8609840
163 + 8609677 = 8609840
193 + 8609647 = 8609840
223 + 8609617 = 8609840
229 + 8609611 = 8609840
271 + 8609569 = 8609840

Showing the first eight; more decompositions exist.
