Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647998, here are decompositions:

5 + 8647993 = 8647998
19 + 8647979 = 8647998
31 + 8647967 = 8647998
61 + 8647937 = 8647998
71 + 8647927 = 8647998
101 + 8647897 = 8647998
109 + 8647889 = 8647998
179 + 8647819 = 8647998

Showing the first eight; more decompositions exist.
