Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51918, here are decompositions:
- 5 + 51913 = 51918
- 11 + 51907 = 51918
- 19 + 51899 = 51918
- 47 + 51871 = 51918
- 59 + 51859 = 51918
- 79 + 51839 = 51918
- 89 + 51829 = 51918
- 101 + 51817 = 51918
Showing the first eight; more decompositions exist.
