Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15432, here are decompositions:
- 5 + 15427 = 15432
- 19 + 15413 = 15432
- 31 + 15401 = 15432
- 41 + 15391 = 15432
- 59 + 15373 = 15432
- 71 + 15361 = 15432
- 73 + 15359 = 15432
- 83 + 15349 = 15432
Showing the first eight; more decompositions exist.
