Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29970, here are decompositions:
- 11 + 29959 = 29970
- 23 + 29947 = 29970
- 43 + 29927 = 29970
- 53 + 29917 = 29970
- 89 + 29881 = 29970
- 97 + 29873 = 29970
- 103 + 29867 = 29970
- 107 + 29863 = 29970
Showing the first eight; more decompositions exist.
