Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618320, here are decompositions:

3 + 8618317 = 8618320
23 + 8618297 = 8618320
47 + 8618273 = 8618320
83 + 8618237 = 8618320
107 + 8618213 = 8618320
173 + 8618147 = 8618320
233 + 8618087 = 8618320
257 + 8618063 = 8618320

Showing the first eight; more decompositions exist.
