Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2068, here are decompositions:
- 5 + 2063 = 2068
- 29 + 2039 = 2068
- 41 + 2027 = 2068
- 71 + 1997 = 2068
- 89 + 1979 = 2068
- 137 + 1931 = 2068
- 167 + 1901 = 2068
- 179 + 1889 = 2068
Showing the first eight; more decompositions exist.
