Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13156, here are decompositions:

5 + 13151 = 13156
29 + 13127 = 13156
47 + 13109 = 13156
53 + 13103 = 13156
107 + 13049 = 13156
113 + 13043 = 13156
149 + 13007 = 13156
173 + 12983 = 13156

Showing the first eight; more decompositions exist.
