Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178254, here are decompositions:

5 + 178249 = 178254
7 + 178247 = 178254
23 + 178231 = 178254
31 + 178223 = 178254
47 + 178207 = 178254
67 + 178187 = 178254
71 + 178183 = 178254
103 + 178151 = 178254

Showing the first eight; more decompositions exist.
