Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25494, here are decompositions:
- 23 + 25471 = 25494
- 31 + 25463 = 25494
- 37 + 25457 = 25494
- 41 + 25453 = 25494
- 47 + 25447 = 25494
- 71 + 25423 = 25494
- 83 + 25411 = 25494
- 103 + 25391 = 25494
Showing the first eight; more decompositions exist.
