Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669946, here are decompositions:

7 + 8669939 = 8669946
17 + 8669929 = 8669946
23 + 8669923 = 8669946
53 + 8669893 = 8669946
67 + 8669879 = 8669946
179 + 8669767 = 8669946
277 + 8669669 = 8669946
317 + 8669629 = 8669946

Showing the first eight; more decompositions exist.
