Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669402, here are decompositions:

3 + 8669399 = 8669402
13 + 8669389 = 8669402
61 + 8669341 = 8669402
73 + 8669329 = 8669402
109 + 8669293 = 8669402
151 + 8669251 = 8669402
163 + 8669239 = 8669402
223 + 8669179 = 8669402

Showing the first eight; more decompositions exist.
