Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51868, here are decompositions:
- 29 + 51839 = 51868
- 41 + 51827 = 51868
- 71 + 51797 = 51868
- 101 + 51767 = 51868
- 149 + 51719 = 51868
- 269 + 51599 = 51868
- 317 + 51551 = 51868
- 347 + 51521 = 51868
Showing the first eight; more decompositions exist.
