Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669666, here are decompositions:

37 + 8669629 = 8669666
43 + 8669623 = 8669666
73 + 8669593 = 8669666
139 + 8669527 = 8669666
223 + 8669443 = 8669666
277 + 8669389 = 8669666
337 + 8669329 = 8669666
349 + 8669317 = 8669666

Showing the first eight; more decompositions exist.
