Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23728, here are decompositions:
- 41 + 23687 = 23728
- 59 + 23669 = 23728
- 101 + 23627 = 23728
- 167 + 23561 = 23728
- 179 + 23549 = 23728
- 191 + 23537 = 23728
- 197 + 23531 = 23728
- 269 + 23459 = 23728
Showing the first eight; more decompositions exist.
