Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25600, here are decompositions:
- 11 + 25589 = 25600
- 17 + 25583 = 25600
- 23 + 25577 = 25600
- 59 + 25541 = 25600
- 131 + 25469 = 25600
- 137 + 25463 = 25600
- 191 + 25409 = 25600
- 227 + 25373 = 25600
Showing the first eight; more decompositions exist.
