Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19428, here are decompositions:

5 + 19423 = 19428
7 + 19421 = 19428
11 + 19417 = 19428
37 + 19391 = 19428
41 + 19387 = 19428
47 + 19381 = 19428
109 + 19319 = 19428
127 + 19301 = 19428

Showing the first eight; more decompositions exist.
