Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143446, here are decompositions:
- 3 + 143443 = 143446
- 59 + 143387 = 143446
- 89 + 143357 = 143446
- 113 + 143333 = 143446
- 197 + 143249 = 143446
- 269 + 143177 = 143446
- 353 + 143093 = 143446
- 383 + 143063 = 143446
Showing the first eight; more decompositions exist.
