Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609420, here are decompositions:

67 + 8609353 = 8609420
73 + 8609347 = 8609420
97 + 8609323 = 8609420
139 + 8609281 = 8609420
151 + 8609269 = 8609420
163 + 8609257 = 8609420
181 + 8609239 = 8609420
271 + 8609149 = 8609420

Showing the first eight; more decompositions exist.
