Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178268, here are decompositions:
- 7 + 178261 = 178268
- 19 + 178249 = 178268
- 37 + 178231 = 178268
- 61 + 178207 = 178268
- 127 + 178141 = 178268
- 151 + 178117 = 178268
- 199 + 178069 = 178268
- 229 + 178039 = 178268
Showing the first eight; more decompositions exist.
