Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129434, here are decompositions:
- 31 + 129403 = 129434
- 73 + 129361 = 129434
- 157 + 129277 = 129434
- 211 + 129223 = 129434
- 241 + 129193 = 129434
- 307 + 129127 = 129434
- 313 + 129121 = 129434
- 337 + 129097 = 129434
Showing the first eight; more decompositions exist.
