Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170258, here are decompositions:
- 19 + 170239 = 170258
- 31 + 170227 = 170258
- 61 + 170197 = 170258
- 79 + 170179 = 170258
- 157 + 170101 = 170258
- 211 + 170047 = 170258
- 229 + 170029 = 170258
- 271 + 169987 = 170258
Showing the first eight; more decompositions exist.
