Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668998, here are decompositions:

5 + 8668993 = 8668998
31 + 8668967 = 8668998
47 + 8668951 = 8668998
97 + 8668901 = 8668998
101 + 8668897 = 8668998
109 + 8668889 = 8668998
167 + 8668831 = 8668998
181 + 8668817 = 8668998

Showing the first eight; more decompositions exist.
