Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67216, here are decompositions:
- 3 + 67213 = 67216
- 5 + 67211 = 67216
- 29 + 67187 = 67216
- 47 + 67169 = 67216
- 59 + 67157 = 67216
- 113 + 67103 = 67216
- 137 + 67079 = 67216
- 167 + 67049 = 67216
Showing the first eight; more decompositions exist.
