Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68128, here are decompositions:
- 17 + 68111 = 68128
- 29 + 68099 = 68128
- 41 + 68087 = 68128
- 149 + 67979 = 68128
- 167 + 67961 = 68128
- 197 + 67931 = 68128
- 227 + 67901 = 68128
- 419 + 67709 = 68128
Showing the first eight; more decompositions exist.
