Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66998, here are decompositions:
- 67 + 66931 = 66998
- 79 + 66919 = 66998
- 109 + 66889 = 66998
- 157 + 66841 = 66998
- 277 + 66721 = 66998
- 397 + 66601 = 66998
- 457 + 66541 = 66998
- 499 + 66499 = 66998
Showing the first eight; more decompositions exist.
