Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19408, here are decompositions:

5 + 19403 = 19408
17 + 19391 = 19408
29 + 19379 = 19408
89 + 19319 = 19408
107 + 19301 = 19408
149 + 19259 = 19408
197 + 19211 = 19408
227 + 19181 = 19408

Showing the first eight; more decompositions exist.
