Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25524, here are decompositions:
- 53 + 25471 = 25524
- 61 + 25463 = 25524
- 67 + 25457 = 25524
- 71 + 25453 = 25524
- 101 + 25423 = 25524
- 113 + 25411 = 25524
- 151 + 25373 = 25524
- 157 + 25367 = 25524
Showing the first eight; more decompositions exist.
