Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2022, here are decompositions:
- 5 + 2017 = 2022
- 11 + 2011 = 2022
- 19 + 2003 = 2022
- 23 + 1999 = 2022
- 29 + 1993 = 2022
- 43 + 1979 = 2022
- 71 + 1951 = 2022
- 73 + 1949 = 2022
Showing the first eight; more decompositions exist.
