Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669448, here are decompositions:

5 + 8669443 = 8669448
31 + 8669417 = 8669448
37 + 8669411 = 8669448
59 + 8669389 = 8669448
97 + 8669351 = 8669448
107 + 8669341 = 8669448
131 + 8669317 = 8669448
197 + 8669251 = 8669448

Showing the first eight; more decompositions exist.
