Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169258, here are decompositions:
- 17 + 169241 = 169258
- 41 + 169217 = 169258
- 59 + 169199 = 169258
- 107 + 169151 = 169258
- 179 + 169079 = 169258
- 191 + 169067 = 169258
- 239 + 169019 = 169258
- 251 + 169007 = 169258
Showing the first eight; more decompositions exist.
