Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609372, here are decompositions:

19 + 8609353 = 8609372
103 + 8609269 = 8609372
199 + 8609173 = 8609372
223 + 8609149 = 8609372
349 + 8609023 = 8609372
463 + 8608909 = 8609372
571 + 8608801 = 8609372
601 + 8608771 = 8609372

Showing the first eight; more decompositions exist.
