Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25502, here are decompositions:
- 31 + 25471 = 25502
- 79 + 25423 = 25502
- 163 + 25339 = 25502
- 181 + 25321 = 25502
- 193 + 25309 = 25502
- 199 + 25303 = 25502
- 241 + 25261 = 25502
- 283 + 25219 = 25502
Showing the first eight; more decompositions exist.
