Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2058, here are decompositions:
- 5 + 2053 = 2058
- 19 + 2039 = 2058
- 29 + 2029 = 2058
- 31 + 2027 = 2058
- 41 + 2017 = 2058
- 47 + 2011 = 2058
- 59 + 1999 = 2058
- 61 + 1997 = 2058
Showing the first eight; more decompositions exist.
