Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609320, here are decompositions:

11 + 8609309 = 8609320
23 + 8609297 = 8609320
47 + 8609273 = 8609320
113 + 8609207 = 8609320
191 + 8609129 = 8609320
227 + 8609093 = 8609320
233 + 8609087 = 8609320
257 + 8609063 = 8609320

Showing the first eight; more decompositions exist.
