Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68006, here are decompositions:
- 13 + 67993 = 68006
- 19 + 67987 = 68006
- 67 + 67939 = 68006
- 73 + 67933 = 68006
- 79 + 67927 = 68006
- 139 + 67867 = 68006
- 163 + 67843 = 68006
- 199 + 67807 = 68006
Showing the first eight; more decompositions exist.
