Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13210, here are decompositions:

23 + 13187 = 13210
47 + 13163 = 13210
59 + 13151 = 13210
83 + 13127 = 13210
89 + 13121 = 13210
101 + 13109 = 13210
107 + 13103 = 13210
167 + 13043 = 13210

Showing the first eight; more decompositions exist.
