Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25756, here are decompositions:
- 23 + 25733 = 25756
- 53 + 25703 = 25756
- 83 + 25673 = 25756
- 89 + 25667 = 25756
- 113 + 25643 = 25756
- 167 + 25589 = 25756
- 173 + 25583 = 25756
- 179 + 25577 = 25756
Showing the first eight; more decompositions exist.
