Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13144, here are decompositions:

17 + 13127 = 13144
23 + 13121 = 13144
41 + 13103 = 13144
101 + 13043 = 13144
107 + 13037 = 13144
137 + 13007 = 13144
191 + 12953 = 13144
227 + 12917 = 13144

Showing the first eight; more decompositions exist.
