Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19340, here are decompositions:

7 + 19333 = 19340
31 + 19309 = 19340
67 + 19273 = 19340
73 + 19267 = 19340
103 + 19237 = 19340
109 + 19231 = 19340
127 + 19213 = 19340
157 + 19183 = 19340

Showing the first eight; more decompositions exist.
