Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68992, here are decompositions:
- 29 + 68963 = 68992
- 83 + 68909 = 68992
- 89 + 68903 = 68992
- 101 + 68891 = 68992
- 113 + 68879 = 68992
- 173 + 68819 = 68992
- 179 + 68813 = 68992
- 263 + 68729 = 68992
Showing the first eight; more decompositions exist.
