Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628766, here are decompositions:

89 + 8628677 = 8628766
137 + 8628629 = 8628766
317 + 8628449 = 8628766
359 + 8628407 = 8628766
383 + 8628383 = 8628766
389 + 8628377 = 8628766
563 + 8628203 = 8628766
593 + 8628173 = 8628766

Showing the first eight; more decompositions exist.
