Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71982, here are decompositions:
- 11 + 71971 = 71982
- 19 + 71963 = 71982
- 41 + 71941 = 71982
- 73 + 71909 = 71982
- 83 + 71899 = 71982
- 101 + 71881 = 71982
- 103 + 71879 = 71982
- 139 + 71843 = 71982
Showing the first eight; more decompositions exist.
