Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23542, here are decompositions:
- 3 + 23539 = 23542
- 5 + 23537 = 23542
- 11 + 23531 = 23542
- 83 + 23459 = 23542
- 173 + 23369 = 23542
- 251 + 23291 = 23542
- 263 + 23279 = 23542
- 353 + 23189 = 23542
Showing the first eight; more decompositions exist.
