Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25884, here are decompositions:
- 11 + 25873 = 25884
- 17 + 25867 = 25884
- 37 + 25847 = 25884
- 43 + 25841 = 25884
- 83 + 25801 = 25884
- 113 + 25771 = 25884
- 137 + 25747 = 25884
- 151 + 25733 = 25884
Showing the first eight; more decompositions exist.
