Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13146, here are decompositions:

19 + 13127 = 13146
37 + 13109 = 13146
43 + 13103 = 13146
47 + 13099 = 13146
53 + 13093 = 13146
83 + 13063 = 13146
97 + 13049 = 13146
103 + 13043 = 13146

Showing the first eight; more decompositions exist.
