Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691448, here are decompositions:

41 + 8691407 = 8691448
89 + 8691359 = 8691448
149 + 8691299 = 8691448
167 + 8691281 = 8691448
179 + 8691269 = 8691448
197 + 8691251 = 8691448
239 + 8691209 = 8691448
281 + 8691167 = 8691448

Showing the first eight; more decompositions exist.
