Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25404, here are decompositions:
- 13 + 25391 = 25404
- 31 + 25373 = 25404
- 37 + 25367 = 25404
- 47 + 25357 = 25404
- 61 + 25343 = 25404
- 83 + 25321 = 25404
- 97 + 25307 = 25404
- 101 + 25303 = 25404
Showing the first eight; more decompositions exist.
