Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127438, here are decompositions:
- 107 + 127331 = 127438
- 137 + 127301 = 127438
- 149 + 127289 = 127438
- 167 + 127271 = 127438
- 191 + 127247 = 127438
- 197 + 127241 = 127438
- 281 + 127157 = 127438
- 359 + 127079 = 127438
Showing the first eight; more decompositions exist.
