Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65884, here are decompositions:
- 3 + 65881 = 65884
- 17 + 65867 = 65884
- 41 + 65843 = 65884
- 47 + 65837 = 65884
- 53 + 65831 = 65884
- 107 + 65777 = 65884
- 167 + 65717 = 65884
- 197 + 65687 = 65884
Showing the first eight; more decompositions exist.
