Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19350, here are decompositions:

17 + 19333 = 19350
31 + 19319 = 19350
41 + 19309 = 19350
61 + 19289 = 19350
83 + 19267 = 19350
101 + 19249 = 19350
113 + 19237 = 19350
131 + 19219 = 19350

Showing the first eight; more decompositions exist.
