Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25560, here are decompositions:
- 19 + 25541 = 25560
- 23 + 25537 = 25560
- 37 + 25523 = 25560
- 89 + 25471 = 25560
- 97 + 25463 = 25560
- 103 + 25457 = 25560
- 107 + 25453 = 25560
- 113 + 25447 = 25560
Showing the first eight; more decompositions exist.
