Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669986, here are decompositions:

5 + 8669981 = 8669986
23 + 8669963 = 8669986
47 + 8669939 = 8669986
89 + 8669897 = 8669986
107 + 8669879 = 8669986
317 + 8669669 = 8669986
359 + 8669627 = 8669986
443 + 8669543 = 8669986

Showing the first eight; more decompositions exist.
