Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19458, here are decompositions:

11 + 19447 = 19458
17 + 19441 = 19458
29 + 19429 = 19458
31 + 19427 = 19458
37 + 19421 = 19458
41 + 19417 = 19458
67 + 19391 = 19458
71 + 19387 = 19458

Showing the first eight; more decompositions exist.
