Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68018, here are decompositions:
- 31 + 67987 = 68018
- 61 + 67957 = 68018
- 79 + 67939 = 68018
- 127 + 67891 = 68018
- 151 + 67867 = 68018
- 199 + 67819 = 68018
- 211 + 67807 = 68018
- 229 + 67789 = 68018
Showing the first eight; more decompositions exist.
