Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669486, here are decompositions:

3 + 8669483 = 8669486
43 + 8669443 = 8669486
97 + 8669389 = 8669486
157 + 8669329 = 8669486
193 + 8669293 = 8669486
307 + 8669179 = 8669486
373 + 8669113 = 8669486
379 + 8669107 = 8669486

Showing the first eight; more decompositions exist.
