Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19108, here are decompositions:

29 + 19079 = 19108
71 + 19037 = 19108
107 + 19001 = 19108
149 + 18959 = 19108
191 + 18917 = 19108
197 + 18911 = 19108
239 + 18869 = 19108
269 + 18839 = 19108

Showing the first eight; more decompositions exist.
