Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68816, here are decompositions:
- 3 + 68813 = 68816
- 67 + 68749 = 68816
- 73 + 68743 = 68816
- 79 + 68737 = 68816
- 103 + 68713 = 68816
- 157 + 68659 = 68816
- 277 + 68539 = 68816
- 367 + 68449 = 68816
Showing the first eight; more decompositions exist.
