Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655448, here are decompositions:

47 + 8655401 = 8655448
251 + 8655197 = 8655448
281 + 8655167 = 8655448
401 + 8655047 = 8655448
419 + 8655029 = 8655448
467 + 8654981 = 8655448
677 + 8654771 = 8655448
719 + 8654729 = 8655448

Showing the first eight; more decompositions exist.
