Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13184, here are decompositions:

7 + 13177 = 13184
13 + 13171 = 13184
37 + 13147 = 13184
151 + 13033 = 13184
181 + 13003 = 13184
211 + 12973 = 13184
277 + 12907 = 13184
331 + 12853 = 13184

Showing the first eight; more decompositions exist.
