Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28432, here are decompositions:
- 3 + 28429 = 28432
- 23 + 28409 = 28432
- 29 + 28403 = 28432
- 83 + 28349 = 28432
- 113 + 28319 = 28432
- 149 + 28283 = 28432
- 251 + 28181 = 28432
- 269 + 28163 = 28432
Showing the first eight; more decompositions exist.
