Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139958, here are decompositions:
- 19 + 139939 = 139958
- 37 + 139921 = 139958
- 67 + 139891 = 139958
- 97 + 139861 = 139958
- 127 + 139831 = 139958
- 157 + 139801 = 139958
- 199 + 139759 = 139958
- 211 + 139747 = 139958
Showing the first eight; more decompositions exist.
