Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178304, here are decompositions:

3 + 178301 = 178304
43 + 178261 = 178304
73 + 178231 = 178304
97 + 178207 = 178304
163 + 178141 = 178304
211 + 178093 = 178304
283 + 178021 = 178304
337 + 177967 = 178304

Showing the first eight; more decompositions exist.
