Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178384, here are decompositions:
- 23 + 178361 = 178384
- 83 + 178301 = 178384
- 137 + 178247 = 178384
- 197 + 178187 = 178384
- 233 + 178151 = 178384
- 257 + 178127 = 178384
- 281 + 178103 = 178384
- 293 + 178091 = 178384
Showing the first eight; more decompositions exist.
