Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91402, here are decompositions:
- 5 + 91397 = 91402
- 29 + 91373 = 91402
- 71 + 91331 = 91402
- 149 + 91253 = 91402
- 173 + 91229 = 91402
- 239 + 91163 = 91402
- 251 + 91151 = 91402
- 263 + 91139 = 91402
Showing the first eight; more decompositions exist.
