Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609442, here are decompositions:

11 + 8609431 = 8609442
31 + 8609411 = 8609442
71 + 8609371 = 8609442
89 + 8609353 = 8609442
109 + 8609333 = 8609442
173 + 8609269 = 8609442
269 + 8609173 = 8609442
293 + 8609149 = 8609442

Showing the first eight; more decompositions exist.
