Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609042, here are decompositions:

19 + 8609023 = 8609042
151 + 8608891 = 8609042
163 + 8608879 = 8609042
181 + 8608861 = 8609042
241 + 8608801 = 8609042
271 + 8608771 = 8609042
283 + 8608759 = 8609042
433 + 8608609 = 8609042

Showing the first eight; more decompositions exist.
