Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16438, here are decompositions:

5 + 16433 = 16438
11 + 16427 = 16438
17 + 16421 = 16438
89 + 16349 = 16438
137 + 16301 = 16438
251 + 16187 = 16438
311 + 16127 = 16438
347 + 16091 = 16438

Showing the first eight; more decompositions exist.
