Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13378, here are decompositions:

11 + 13367 = 13378
41 + 13337 = 13378
47 + 13331 = 13378
137 + 13241 = 13378
149 + 13229 = 13378
191 + 13187 = 13378
227 + 13151 = 13378
251 + 13127 = 13378

Showing the first eight; more decompositions exist.
