Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68978, here are decompositions:
- 31 + 68947 = 68978
- 61 + 68917 = 68978
- 79 + 68899 = 68978
- 97 + 68881 = 68978
- 157 + 68821 = 68978
- 211 + 68767 = 68978
- 229 + 68749 = 68978
- 241 + 68737 = 68978
Showing the first eight; more decompositions exist.
