Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609078, here are decompositions:

199 + 8608879 = 8609078
241 + 8608837 = 8609078
277 + 8608801 = 8609078
307 + 8608771 = 8609078
487 + 8608591 = 8609078
571 + 8608507 = 8609078
757 + 8608321 = 8609078
787 + 8608291 = 8609078

Showing the first eight; more decompositions exist.
