Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643798, here are decompositions:

11 + 8643787 = 8643798
19 + 8643779 = 8643798
41 + 8643757 = 8643798
101 + 8643697 = 8643798
127 + 8643671 = 8643798
151 + 8643647 = 8643798
167 + 8643631 = 8643798
179 + 8643619 = 8643798

Showing the first eight; more decompositions exist.
