Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19394, here are decompositions:

3 + 19391 = 19394
7 + 19387 = 19394
13 + 19381 = 19394
61 + 19333 = 19394
127 + 19267 = 19394
157 + 19237 = 19394
163 + 19231 = 19394
181 + 19213 = 19394

Showing the first eight; more decompositions exist.
