Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669404, here are decompositions:

5 + 8669399 = 8669404
11 + 8669393 = 8669404
53 + 8669351 = 8669404
71 + 8669333 = 8669404
167 + 8669237 = 8669404
197 + 8669207 = 8669404
281 + 8669123 = 8669404
431 + 8668973 = 8669404

Showing the first eight; more decompositions exist.
