Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127144, here are decompositions:
- 5 + 127139 = 127144
- 11 + 127133 = 127144
- 41 + 127103 = 127144
- 107 + 127037 = 127144
- 113 + 127031 = 127144
- 293 + 126851 = 127144
- 317 + 126827 = 127144
- 383 + 126761 = 127144
Showing the first eight; more decompositions exist.
