Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639448, here are decompositions:

5 + 8639443 = 8639448
7 + 8639441 = 8639448
47 + 8639401 = 8639448
67 + 8639381 = 8639448
101 + 8639347 = 8639448
149 + 8639299 = 8639448
157 + 8639291 = 8639448
197 + 8639251 = 8639448

Showing the first eight; more decompositions exist.
