Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19208, here are decompositions:

67 + 19141 = 19208
127 + 19081 = 19208
139 + 19069 = 19208
157 + 19051 = 19208
199 + 19009 = 19208
229 + 18979 = 19208
349 + 18859 = 19208
421 + 18787 = 19208

Showing the first eight; more decompositions exist.
