Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19164, here are decompositions:

7 + 19157 = 19164
23 + 19141 = 19164
43 + 19121 = 19164
83 + 19081 = 19164
113 + 19051 = 19164
127 + 19037 = 19164
151 + 19013 = 19164
163 + 19001 = 19164

Showing the first eight; more decompositions exist.
