Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19356, here are decompositions:

23 + 19333 = 19356
37 + 19319 = 19356
47 + 19309 = 19356
67 + 19289 = 19356
83 + 19273 = 19356
89 + 19267 = 19356
97 + 19259 = 19356
107 + 19249 = 19356

Showing the first eight; more decompositions exist.
