Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42122, here are decompositions:
- 61 + 42061 = 42122
- 79 + 42043 = 42122
- 103 + 42019 = 42122
- 109 + 42013 = 42122
- 139 + 41983 = 42122
- 163 + 41959 = 42122
- 181 + 41941 = 42122
- 211 + 41911 = 42122
Showing the first eight; more decompositions exist.
