Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178366, here are decompositions:

5 + 178361 = 178366
17 + 178349 = 178366
59 + 178307 = 178366
107 + 178259 = 178366
179 + 178187 = 178366
197 + 178169 = 178366
239 + 178127 = 178366
263 + 178103 = 178366

Showing the first eight; more decompositions exist.
