Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178238, here are decompositions:
- 7 + 178231 = 178238
- 31 + 178207 = 178238
- 97 + 178141 = 178238
- 199 + 178039 = 178238
- 271 + 177967 = 178238
- 331 + 177907 = 178238
- 349 + 177889 = 178238
- 397 + 177841 = 178238
Showing the first eight; more decompositions exist.
