Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65856, here are decompositions:
- 5 + 65851 = 65856
- 13 + 65843 = 65856
- 17 + 65839 = 65856
- 19 + 65837 = 65856
- 29 + 65827 = 65856
- 47 + 65809 = 65856
- 67 + 65789 = 65856
- 79 + 65777 = 65856
Showing the first eight; more decompositions exist.
