Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25724, here are decompositions:
- 7 + 25717 = 25724
- 31 + 25693 = 25724
- 67 + 25657 = 25724
- 103 + 25621 = 25724
- 163 + 25561 = 25724
- 271 + 25453 = 25724
- 277 + 25447 = 25724
- 313 + 25411 = 25724
Showing the first eight; more decompositions exist.
