Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2122, here are decompositions:
- 11 + 2111 = 2122
- 23 + 2099 = 2122
- 41 + 2081 = 2122
- 53 + 2069 = 2122
- 59 + 2063 = 2122
- 83 + 2039 = 2122
- 149 + 1973 = 2122
- 173 + 1949 = 2122
Showing the first eight; more decompositions exist.
