Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669412, here are decompositions:

13 + 8669399 = 8669412
19 + 8669393 = 8669412
23 + 8669389 = 8669412
61 + 8669351 = 8669412
71 + 8669341 = 8669412
79 + 8669333 = 8669412
83 + 8669329 = 8669412
163 + 8669249 = 8669412

Showing the first eight; more decompositions exist.
