Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13284, here are decompositions:

17 + 13267 = 13284
43 + 13241 = 13284
67 + 13217 = 13284
97 + 13187 = 13284
101 + 13183 = 13284
107 + 13177 = 13284
113 + 13171 = 13284
137 + 13147 = 13284

Showing the first eight; more decompositions exist.
