Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669408, here are decompositions:

19 + 8669389 = 8669408
67 + 8669341 = 8669408
79 + 8669329 = 8669408
157 + 8669251 = 8669408
229 + 8669179 = 8669408
337 + 8669071 = 8669408
367 + 8669041 = 8669408
457 + 8668951 = 8669408

Showing the first eight; more decompositions exist.
