Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25856, here are decompositions:
- 7 + 25849 = 25856
- 37 + 25819 = 25856
- 97 + 25759 = 25856
- 109 + 25747 = 25856
- 139 + 25717 = 25856
- 163 + 25693 = 25856
- 199 + 25657 = 25856
- 223 + 25633 = 25856
Showing the first eight; more decompositions exist.
