Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647984, here are decompositions:

5 + 8647979 = 8647984
17 + 8647967 = 8647984
47 + 8647937 = 8647984
71 + 8647913 = 8647984
167 + 8647817 = 8647984
593 + 8647391 = 8647984
617 + 8647367 = 8647984
827 + 8647157 = 8647984

Showing the first eight; more decompositions exist.
