Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51166, here are decompositions:
- 29 + 51137 = 51166
- 107 + 51059 = 51166
- 173 + 50993 = 51166
- 197 + 50969 = 51166
- 257 + 50909 = 51166
- 293 + 50873 = 51166
- 317 + 50849 = 51166
- 389 + 50777 = 51166
Showing the first eight; more decompositions exist.
