Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23180, here are decompositions:
- 7 + 23173 = 23180
- 13 + 23167 = 23180
- 37 + 23143 = 23180
- 109 + 23071 = 23180
- 127 + 23053 = 23180
- 139 + 23041 = 23180
- 151 + 23029 = 23180
- 163 + 23017 = 23180
Showing the first eight; more decompositions exist.
