Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165704, here are decompositions:
- 3 + 165701 = 165704
- 31 + 165673 = 165704
- 37 + 165667 = 165704
- 103 + 165601 = 165704
- 151 + 165553 = 165704
- 163 + 165541 = 165704
- 181 + 165523 = 165704
- 193 + 165511 = 165704
Showing the first eight; more decompositions exist.
