Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25864, here are decompositions:
- 17 + 25847 = 25864
- 23 + 25841 = 25864
- 71 + 25793 = 25864
- 101 + 25763 = 25864
- 131 + 25733 = 25864
- 191 + 25673 = 25864
- 197 + 25667 = 25864
- 263 + 25601 = 25864
Showing the first eight; more decompositions exist.
