Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640934, here are decompositions:

23 + 8640911 = 8640934
47 + 8640887 = 8640934
167 + 8640767 = 8640934
173 + 8640761 = 8640934
227 + 8640707 = 8640934
233 + 8640701 = 8640934
251 + 8640683 = 8640934
347 + 8640587 = 8640934

Showing the first eight; more decompositions exist.
