Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16458, here are decompositions:
- 5 + 16453 = 16458
- 7 + 16451 = 16458
- 11 + 16447 = 16458
- 31 + 16427 = 16458
- 37 + 16421 = 16458
- 41 + 16417 = 16458
- 47 + 16411 = 16458
- 89 + 16369 = 16458
Showing the first eight; more decompositions exist.
