Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669480, here are decompositions:

3 + 8669477 = 8669480
37 + 8669443 = 8669480
139 + 8669341 = 8669480
151 + 8669329 = 8669480
163 + 8669317 = 8669480
229 + 8669251 = 8669480
241 + 8669239 = 8669480
367 + 8669113 = 8669480

Showing the first eight; more decompositions exist.
