Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25918, here are decompositions:
- 5 + 25913 = 25918
- 29 + 25889 = 25918
- 71 + 25847 = 25918
- 239 + 25679 = 25918
- 251 + 25667 = 25918
- 317 + 25601 = 25918
- 449 + 25469 = 25918
- 461 + 25457 = 25918
Showing the first eight; more decompositions exist.
