Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6458, here are decompositions:
- 7 + 6451 = 6458
- 31 + 6427 = 6458
- 37 + 6421 = 6458
- 61 + 6397 = 6458
- 79 + 6379 = 6458
- 97 + 6361 = 6458
- 157 + 6301 = 6458
- 181 + 6277 = 6458
Showing the first eight; more decompositions exist.
