Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669400, here are decompositions:

7 + 8669393 = 8669400
11 + 8669389 = 8669400
59 + 8669341 = 8669400
67 + 8669333 = 8669400
71 + 8669329 = 8669400
83 + 8669317 = 8669400
107 + 8669293 = 8669400
149 + 8669251 = 8669400

Showing the first eight; more decompositions exist.
