Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19136, here are decompositions:

67 + 19069 = 19136
127 + 19009 = 19136
157 + 18979 = 19136
163 + 18973 = 19136
223 + 18913 = 19136
277 + 18859 = 19136
349 + 18787 = 19136
379 + 18757 = 19136

Showing the first eight; more decompositions exist.
