Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663320, here are decompositions:

11 + 8663309 = 8663320
41 + 8663279 = 8663320
47 + 8663273 = 8663320
59 + 8663261 = 8663320
167 + 8663153 = 8663320
227 + 8663093 = 8663320
317 + 8663003 = 8663320
431 + 8662889 = 8663320

Showing the first eight; more decompositions exist.
