Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143458, here are decompositions:
- 71 + 143387 = 143458
- 101 + 143357 = 143458
- 167 + 143291 = 143458
- 197 + 143261 = 143458
- 281 + 143177 = 143458
- 317 + 143141 = 143458
- 347 + 143111 = 143458
- 479 + 142979 = 143458
Showing the first eight; more decompositions exist.
