Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627320, here are decompositions:

167 + 8627153 = 8627320
173 + 8627147 = 8627320
179 + 8627141 = 8627320
239 + 8627081 = 8627320
263 + 8627057 = 8627320
269 + 8627051 = 8627320
419 + 8626901 = 8627320
479 + 8626841 = 8627320

Showing the first eight; more decompositions exist.
