Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669686, here are decompositions:

17 + 8669669 = 8669686
29 + 8669657 = 8669686
59 + 8669627 = 8669686
173 + 8669513 = 8669686
197 + 8669489 = 8669686
239 + 8669447 = 8669686
269 + 8669417 = 8669686
293 + 8669393 = 8669686

Showing the first eight; more decompositions exist.
