Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25886, here are decompositions:
- 13 + 25873 = 25886
- 19 + 25867 = 25886
- 37 + 25849 = 25886
- 67 + 25819 = 25886
- 127 + 25759 = 25886
- 139 + 25747 = 25886
- 193 + 25693 = 25886
- 229 + 25657 = 25886
Showing the first eight; more decompositions exist.
