Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68864, here are decompositions:
- 43 + 68821 = 68864
- 73 + 68791 = 68864
- 97 + 68767 = 68864
- 127 + 68737 = 68864
- 151 + 68713 = 68864
- 181 + 68683 = 68864
- 283 + 68581 = 68864
- 373 + 68491 = 68864
Showing the first eight; more decompositions exist.
