Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25426, here are decompositions:
- 3 + 25423 = 25426
- 17 + 25409 = 25426
- 53 + 25373 = 25426
- 59 + 25367 = 25426
- 83 + 25343 = 25426
- 173 + 25253 = 25426
- 179 + 25247 = 25426
- 197 + 25229 = 25426
Showing the first eight; more decompositions exist.
