Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669958, here are decompositions:

19 + 8669939 = 8669958
29 + 8669929 = 8669958
47 + 8669911 = 8669958
61 + 8669897 = 8669958
79 + 8669879 = 8669958
97 + 8669861 = 8669958
127 + 8669831 = 8669958
137 + 8669821 = 8669958

Showing the first eight; more decompositions exist.
