Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18026, here are decompositions:

13 + 18013 = 18026
37 + 17989 = 18026
67 + 17959 = 18026
97 + 17929 = 18026
103 + 17923 = 18026
163 + 17863 = 18026
199 + 17827 = 18026
277 + 17749 = 18026

Showing the first eight; more decompositions exist.
