Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81932, here are decompositions:
- 3 + 81929 = 81932
- 13 + 81919 = 81932
- 31 + 81901 = 81932
- 79 + 81853 = 81932
- 163 + 81769 = 81932
- 229 + 81703 = 81932
- 283 + 81649 = 81932
- 313 + 81619 = 81932
Showing the first eight; more decompositions exist.
