Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66782, here are decompositions:
- 19 + 66763 = 66782
- 31 + 66751 = 66782
- 43 + 66739 = 66782
- 61 + 66721 = 66782
- 139 + 66643 = 66782
- 181 + 66601 = 66782
- 211 + 66571 = 66782
- 229 + 66553 = 66782
Showing the first eight; more decompositions exist.
