Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9018, here are decompositions:

5 + 9013 = 9018
7 + 9011 = 9018
11 + 9007 = 9018
17 + 9001 = 9018
19 + 8999 = 9018
47 + 8971 = 9018
67 + 8951 = 9018
89 + 8929 = 9018

Showing the first eight; more decompositions exist.
