Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2048, here are decompositions:
- 19 + 2029 = 2048
- 31 + 2017 = 2048
- 37 + 2011 = 2048
- 61 + 1987 = 2048
- 97 + 1951 = 2048
- 181 + 1867 = 2048
- 271 + 1777 = 2048
- 307 + 1741 = 2048
Showing the first eight; more decompositions exist.
