Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9012, here are decompositions:

5 + 9007 = 9012
11 + 9001 = 9012
13 + 8999 = 9012
41 + 8971 = 9012
43 + 8969 = 9012
61 + 8951 = 9012
71 + 8941 = 9012
79 + 8933 = 9012

Showing the first eight; more decompositions exist.
