Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133458, here are decompositions:
- 7 + 133451 = 133458
- 11 + 133447 = 133458
- 19 + 133439 = 133458
- 41 + 133417 = 133458
- 67 + 133391 = 133458
- 71 + 133387 = 133458
- 79 + 133379 = 133458
- 107 + 133351 = 133458
Showing the first eight; more decompositions exist.
