Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65904, here are decompositions:
- 5 + 65899 = 65904
- 23 + 65881 = 65904
- 37 + 65867 = 65904
- 53 + 65851 = 65904
- 61 + 65843 = 65904
- 67 + 65837 = 65904
- 73 + 65831 = 65904
- 127 + 65777 = 65904
Showing the first eight; more decompositions exist.
