Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129446, here are decompositions:
- 3 + 129443 = 129446
- 7 + 129439 = 129446
- 43 + 129403 = 129446
- 67 + 129379 = 129446
- 157 + 129289 = 129446
- 223 + 129223 = 129446
- 277 + 129169 = 129446
- 349 + 129097 = 129446
Showing the first eight; more decompositions exist.
