Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2086, here are decompositions:
- 3 + 2083 = 2086
- 5 + 2081 = 2086
- 17 + 2069 = 2086
- 23 + 2063 = 2086
- 47 + 2039 = 2086
- 59 + 2027 = 2086
- 83 + 2003 = 2086
- 89 + 1997 = 2086
Showing the first eight; more decompositions exist.
