Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641024, here are decompositions:

17 + 8641007 = 8641024
47 + 8640977 = 8641024
113 + 8640911 = 8641024
137 + 8640887 = 8641024
257 + 8640767 = 8641024
263 + 8640761 = 8641024
311 + 8640713 = 8641024
317 + 8640707 = 8641024

Showing the first eight; more decompositions exist.
