Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13182, here are decompositions:

5 + 13177 = 13182
11 + 13171 = 13182
19 + 13163 = 13182
23 + 13159 = 13182
31 + 13151 = 13182
61 + 13121 = 13182
73 + 13109 = 13182
79 + 13103 = 13182

Showing the first eight; more decompositions exist.
