Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171028, here are decompositions:
- 5 + 171023 = 171028
- 71 + 170957 = 171028
- 101 + 170927 = 171028
- 107 + 170921 = 171028
- 191 + 170837 = 171028
- 227 + 170801 = 171028
- 251 + 170777 = 171028
- 269 + 170759 = 171028
Showing the first eight; more decompositions exist.
