Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165232, here are decompositions:
- 3 + 165229 = 165232
- 29 + 165203 = 165232
- 59 + 165173 = 165232
- 71 + 165161 = 165232
- 149 + 165083 = 165232
- 173 + 165059 = 165232
- 191 + 165041 = 165232
- 233 + 164999 = 165232
Showing the first eight; more decompositions exist.
