Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2028, here are decompositions:
- 11 + 2017 = 2028
- 17 + 2011 = 2028
- 29 + 1999 = 2028
- 31 + 1997 = 2028
- 41 + 1987 = 2028
- 79 + 1949 = 2028
- 97 + 1931 = 2028
- 127 + 1901 = 2028
Showing the first eight; more decompositions exist.
