Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19306, here are decompositions:

5 + 19301 = 19306
17 + 19289 = 19306
47 + 19259 = 19306
149 + 19157 = 19306
167 + 19139 = 19306
227 + 19079 = 19306
233 + 19073 = 19306
269 + 19037 = 19306

Showing the first eight; more decompositions exist.
