Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666944, here are decompositions:

5 + 8666939 = 8666944
17 + 8666927 = 8666944
53 + 8666891 = 8666944
137 + 8666807 = 8666944
197 + 8666747 = 8666944
233 + 8666711 = 8666944
263 + 8666681 = 8666944
317 + 8666627 = 8666944

Showing the first eight; more decompositions exist.
