Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609418, here are decompositions:

7 + 8609411 = 8609418
47 + 8609371 = 8609418
71 + 8609347 = 8609418
109 + 8609309 = 8609418
131 + 8609287 = 8609418
137 + 8609281 = 8609418
149 + 8609269 = 8609418
179 + 8609239 = 8609418

Showing the first eight; more decompositions exist.
