Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25458, here are decompositions:
- 5 + 25453 = 25458
- 11 + 25447 = 25458
- 19 + 25439 = 25458
- 47 + 25411 = 25458
- 67 + 25391 = 25458
- 101 + 25357 = 25458
- 109 + 25349 = 25458
- 137 + 25321 = 25458
Showing the first eight; more decompositions exist.
