Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609540, here are decompositions:

7 + 8609533 = 8609540
67 + 8609473 = 8609540
97 + 8609443 = 8609540
109 + 8609431 = 8609540
193 + 8609347 = 8609540
271 + 8609269 = 8609540
283 + 8609257 = 8609540
367 + 8609173 = 8609540

Showing the first eight; more decompositions exist.
