Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19288, here are decompositions:

29 + 19259 = 19288
107 + 19181 = 19288
131 + 19157 = 19288
149 + 19139 = 19288
167 + 19121 = 19288
251 + 19037 = 19288
257 + 19031 = 19288
389 + 18899 = 19288

Showing the first eight; more decompositions exist.
