Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2056, here are decompositions:
- 3 + 2053 = 2056
- 17 + 2039 = 2056
- 29 + 2027 = 2056
- 53 + 2003 = 2056
- 59 + 1997 = 2056
- 83 + 1973 = 2056
- 107 + 1949 = 2056
- 149 + 1907 = 2056
Showing the first eight; more decompositions exist.
