Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47978, here are decompositions:
- 31 + 47947 = 47978
- 61 + 47917 = 47978
- 67 + 47911 = 47978
- 97 + 47881 = 47978
- 109 + 47869 = 47978
- 181 + 47797 = 47978
- 199 + 47779 = 47978
- 241 + 47737 = 47978
Showing the first eight; more decompositions exist.
