Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13006, here are decompositions:

3 + 13003 = 13006
5 + 13001 = 13006
23 + 12983 = 13006
47 + 12959 = 13006
53 + 12953 = 13006
83 + 12923 = 13006
89 + 12917 = 13006
107 + 12899 = 13006

Showing the first eight; more decompositions exist.
