Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19426, here are decompositions:

3 + 19423 = 19426
5 + 19421 = 19426
23 + 19403 = 19426
47 + 19379 = 19426
53 + 19373 = 19426
107 + 19319 = 19426
137 + 19289 = 19426
167 + 19259 = 19426

Showing the first eight; more decompositions exist.
