Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25868, here are decompositions:
- 19 + 25849 = 25868
- 67 + 25801 = 25868
- 97 + 25771 = 25868
- 109 + 25759 = 25868
- 127 + 25741 = 25868
- 151 + 25717 = 25868
- 211 + 25657 = 25868
- 229 + 25639 = 25868
Showing the first eight; more decompositions exist.
