Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51000, here are decompositions:
- 7 + 50993 = 51000
- 11 + 50989 = 51000
- 29 + 50971 = 51000
- 31 + 50969 = 51000
- 43 + 50957 = 51000
- 71 + 50929 = 51000
- 107 + 50893 = 51000
- 109 + 50891 = 51000
Showing the first eight; more decompositions exist.
