Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25854, here are decompositions:
- 5 + 25849 = 25854
- 7 + 25847 = 25854
- 13 + 25841 = 25854
- 53 + 25801 = 25854
- 61 + 25793 = 25854
- 83 + 25771 = 25854
- 107 + 25747 = 25854
- 113 + 25741 = 25854
Showing the first eight; more decompositions exist.
