Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86944, here are decompositions:
- 5 + 86939 = 86944
- 17 + 86927 = 86944
- 83 + 86861 = 86944
- 101 + 86843 = 86944
- 107 + 86837 = 86944
- 131 + 86813 = 86944
- 173 + 86771 = 86944
- 191 + 86753 = 86944
Showing the first eight; more decompositions exist.
