Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139932, here are decompositions:
- 11 + 139921 = 139932
- 31 + 139901 = 139932
- 41 + 139891 = 139932
- 61 + 139871 = 139932
- 71 + 139861 = 139932
- 101 + 139831 = 139932
- 131 + 139801 = 139932
- 173 + 139759 = 139932
Showing the first eight; more decompositions exist.
