Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127402, here are decompositions:
- 3 + 127399 = 127402
- 29 + 127373 = 127402
- 59 + 127343 = 127402
- 71 + 127331 = 127402
- 101 + 127301 = 127402
- 113 + 127289 = 127402
- 131 + 127271 = 127402
- 239 + 127163 = 127402
Showing the first eight; more decompositions exist.
