Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643448, here are decompositions:

5 + 8643443 = 8643448
89 + 8643359 = 8643448
131 + 8643317 = 8643448
167 + 8643281 = 8643448
239 + 8643209 = 8643448
251 + 8643197 = 8643448
311 + 8643137 = 8643448
389 + 8643059 = 8643448

Showing the first eight; more decompositions exist.
