Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51016, here are decompositions:
- 23 + 50993 = 51016
- 47 + 50969 = 51016
- 59 + 50957 = 51016
- 107 + 50909 = 51016
- 149 + 50867 = 51016
- 167 + 50849 = 51016
- 227 + 50789 = 51016
- 239 + 50777 = 51016
Showing the first eight; more decompositions exist.
