Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25398, here are decompositions:
- 7 + 25391 = 25398
- 31 + 25367 = 25398
- 41 + 25357 = 25398
- 59 + 25339 = 25398
- 89 + 25309 = 25398
- 97 + 25301 = 25398
- 137 + 25261 = 25398
- 151 + 25247 = 25398
Showing the first eight; more decompositions exist.
