Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42168, here are decompositions:
- 11 + 42157 = 42168
- 29 + 42139 = 42168
- 37 + 42131 = 42168
- 67 + 42101 = 42168
- 79 + 42089 = 42168
- 97 + 42071 = 42168
- 107 + 42061 = 42168
- 149 + 42019 = 42168
Showing the first eight; more decompositions exist.
