Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13110, here are decompositions:

7 + 13103 = 13110
11 + 13099 = 13110
17 + 13093 = 13110
47 + 13063 = 13110
61 + 13049 = 13110
67 + 13043 = 13110
73 + 13037 = 13110
101 + 13009 = 13110

Showing the first eight; more decompositions exist.
