Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87458, here are decompositions:
- 31 + 87427 = 87458
- 37 + 87421 = 87458
- 181 + 87277 = 87458
- 271 + 87187 = 87458
- 277 + 87181 = 87458
- 307 + 87151 = 87458
- 337 + 87121 = 87458
- 409 + 87049 = 87458
Showing the first eight; more decompositions exist.
