Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13458, here are decompositions:
- 7 + 13451 = 13458
- 17 + 13441 = 13458
- 37 + 13421 = 13458
- 41 + 13417 = 13458
- 47 + 13411 = 13458
- 59 + 13399 = 13458
- 61 + 13397 = 13458
- 127 + 13331 = 13458
Showing the first eight; more decompositions exist.
