Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669966, here are decompositions:

3 + 8669963 = 8669966
37 + 8669929 = 8669966
43 + 8669923 = 8669966
73 + 8669893 = 8669966
199 + 8669767 = 8669966
337 + 8669629 = 8669966
373 + 8669593 = 8669966
439 + 8669527 = 8669966

Showing the first eight; more decompositions exist.
