Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16432, here are decompositions:
- 5 + 16427 = 16432
- 11 + 16421 = 16432
- 71 + 16361 = 16432
- 83 + 16349 = 16432
- 113 + 16319 = 16432
- 131 + 16301 = 16432
- 179 + 16253 = 16432
- 239 + 16193 = 16432
Showing the first eight; more decompositions exist.
