Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67968, here are decompositions:
- 7 + 67961 = 67968
- 11 + 67957 = 67968
- 29 + 67939 = 67968
- 37 + 67931 = 67968
- 41 + 67927 = 67968
- 67 + 67901 = 67968
- 101 + 67867 = 67968
- 139 + 67829 = 67968
Showing the first eight; more decompositions exist.
