Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18170, here are decompositions:
- 37 + 18133 = 18170
- 43 + 18127 = 18170
- 73 + 18097 = 18170
- 109 + 18061 = 18170
- 127 + 18043 = 18170
- 157 + 18013 = 18170
- 181 + 17989 = 18170
- 193 + 17977 = 18170
Showing the first eight; more decompositions exist.
