Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19238, here are decompositions:

7 + 19231 = 19238
19 + 19219 = 19238
31 + 19207 = 19238
97 + 19141 = 19238
151 + 19087 = 19238
157 + 19081 = 19238
229 + 19009 = 19238
379 + 18859 = 19238

Showing the first eight; more decompositions exist.
