Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13000, here are decompositions:

17 + 12983 = 13000
41 + 12959 = 13000
47 + 12953 = 13000
59 + 12941 = 13000
83 + 12917 = 13000
89 + 12911 = 13000
101 + 12899 = 13000
107 + 12893 = 13000

Showing the first eight; more decompositions exist.
