Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25436, here are decompositions:
- 13 + 25423 = 25436
- 79 + 25357 = 25436
- 97 + 25339 = 25436
- 127 + 25309 = 25436
- 193 + 25243 = 25436
- 199 + 25237 = 25436
- 283 + 25153 = 25436
- 349 + 25087 = 25436
Showing the first eight; more decompositions exist.
