Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19342, here are decompositions:

23 + 19319 = 19342
41 + 19301 = 19342
53 + 19289 = 19342
83 + 19259 = 19342
131 + 19211 = 19342
179 + 19163 = 19342
263 + 19079 = 19342
269 + 19073 = 19342

Showing the first eight; more decompositions exist.
