Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33668, here are decompositions:
- 31 + 33637 = 33668
- 67 + 33601 = 33668
- 79 + 33589 = 33668
- 139 + 33529 = 33668
- 181 + 33487 = 33668
- 199 + 33469 = 33668
- 211 + 33457 = 33668
- 241 + 33427 = 33668
Showing the first eight; more decompositions exist.
