Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646448, here are decompositions:

47 + 8646401 = 8646448
59 + 8646389 = 8646448
71 + 8646377 = 8646448
131 + 8646317 = 8646448
149 + 8646299 = 8646448
179 + 8646269 = 8646448
191 + 8646257 = 8646448
227 + 8646221 = 8646448

Showing the first eight; more decompositions exist.
