Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68016, here are decompositions:
- 23 + 67993 = 68016
- 29 + 67987 = 68016
- 37 + 67979 = 68016
- 59 + 67957 = 68016
- 73 + 67943 = 68016
- 83 + 67933 = 68016
- 89 + 67927 = 68016
- 149 + 67867 = 68016
Showing the first eight; more decompositions exist.
