Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161704, here are decompositions:
- 113 + 161591 = 161704
- 131 + 161573 = 161704
- 173 + 161531 = 161704
- 197 + 161507 = 161704
- 233 + 161471 = 161704
- 251 + 161453 = 161704
- 293 + 161411 = 161704
- 317 + 161387 = 161704
Showing the first eight; more decompositions exist.
