Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609966, here are decompositions:

3 + 8609963 = 8609966
67 + 8609899 = 8609966
193 + 8609773 = 8609966
283 + 8609683 = 8609966
349 + 8609617 = 8609966
397 + 8609569 = 8609966
433 + 8609533 = 8609966
523 + 8609443 = 8609966

Showing the first eight; more decompositions exist.
