Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13170, here are decompositions:

7 + 13163 = 13170
11 + 13159 = 13170
19 + 13151 = 13170
23 + 13147 = 13170
43 + 13127 = 13170
61 + 13109 = 13170
67 + 13103 = 13170
71 + 13099 = 13170

Showing the first eight; more decompositions exist.
