Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709448, here are decompositions:

5 + 8709443 = 8709448
17 + 8709431 = 8709448
71 + 8709377 = 8709448
131 + 8709317 = 8709448
149 + 8709299 = 8709448
191 + 8709257 = 8709448
227 + 8709221 = 8709448
257 + 8709191 = 8709448

Showing the first eight; more decompositions exist.
