Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671448, here are decompositions:

7 + 8671441 = 8671448
67 + 8671381 = 8671448
109 + 8671339 = 8671448
127 + 8671321 = 8671448
157 + 8671291 = 8671448
199 + 8671249 = 8671448
229 + 8671219 = 8671448
271 + 8671177 = 8671448

Showing the first eight; more decompositions exist.
