Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127408, here are decompositions:
- 5 + 127403 = 127408
- 107 + 127301 = 127408
- 131 + 127277 = 127408
- 137 + 127271 = 127408
- 167 + 127241 = 127408
- 191 + 127217 = 127408
- 251 + 127157 = 127408
- 269 + 127139 = 127408
Showing the first eight; more decompositions exist.
