Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16426, here are decompositions:

5 + 16421 = 16426
107 + 16319 = 16426
173 + 16253 = 16426
197 + 16229 = 16426
233 + 16193 = 16426
239 + 16187 = 16426
353 + 16073 = 16426
359 + 16067 = 16426

Showing the first eight; more decompositions exist.
