Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25306, here are decompositions:
- 3 + 25303 = 25306
- 5 + 25301 = 25306
- 53 + 25253 = 25306
- 59 + 25247 = 25306
- 137 + 25169 = 25306
- 179 + 25127 = 25306
- 233 + 25073 = 25306
- 269 + 25037 = 25306
Showing the first eight; more decompositions exist.
