Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169642, here are decompositions:
- 3 + 169639 = 169642
- 59 + 169583 = 169642
- 89 + 169553 = 169642
- 149 + 169493 = 169642
- 233 + 169409 = 169642
- 269 + 169373 = 169642
- 281 + 169361 = 169642
- 359 + 169283 = 169642
Showing the first eight; more decompositions exist.
