Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13542, here are decompositions:
- 5 + 13537 = 13542
- 19 + 13523 = 13542
- 29 + 13513 = 13542
- 43 + 13499 = 13542
- 73 + 13469 = 13542
- 79 + 13463 = 13542
- 101 + 13441 = 13542
- 131 + 13411 = 13542
Showing the first eight; more decompositions exist.
