Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13438, here are decompositions:

17 + 13421 = 13438
41 + 13397 = 13438
71 + 13367 = 13438
101 + 13337 = 13438
107 + 13331 = 13438
179 + 13259 = 13438
197 + 13241 = 13438
251 + 13187 = 13438

Showing the first eight; more decompositions exist.
