Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19388, here are decompositions:

7 + 19381 = 19388
79 + 19309 = 19388
139 + 19249 = 19388
151 + 19237 = 19388
157 + 19231 = 19388
181 + 19207 = 19388
307 + 19081 = 19388
337 + 19051 = 19388

Showing the first eight; more decompositions exist.
