Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170458, here are decompositions:
- 11 + 170447 = 170458
- 17 + 170441 = 170458
- 89 + 170369 = 170458
- 107 + 170351 = 170458
- 131 + 170327 = 170458
- 179 + 170279 = 170458
- 191 + 170267 = 170458
- 227 + 170231 = 170458
Showing the first eight; more decompositions exist.
