Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139968, here are decompositions:
- 29 + 139939 = 139968
- 47 + 139921 = 139968
- 61 + 139907 = 139968
- 67 + 139901 = 139968
- 97 + 139871 = 139968
- 107 + 139861 = 139968
- 131 + 139837 = 139968
- 137 + 139831 = 139968
Showing the first eight; more decompositions exist.
