Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667448, here are decompositions:

17 + 8667431 = 8667448
29 + 8667419 = 8667448
71 + 8667377 = 8667448
149 + 8667299 = 8667448
191 + 8667257 = 8667448
269 + 8667179 = 8667448
281 + 8667167 = 8667448
311 + 8667137 = 8667448

Showing the first eight; more decompositions exist.
