Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25372, here are decompositions:
- 5 + 25367 = 25372
- 23 + 25349 = 25372
- 29 + 25343 = 25372
- 71 + 25301 = 25372
- 251 + 25121 = 25372
- 359 + 25013 = 25372
- 383 + 24989 = 25372
- 401 + 24971 = 25372
Showing the first eight; more decompositions exist.
