Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118180, here are decompositions:
- 11 + 118169 = 118180
- 17 + 118163 = 118180
- 53 + 118127 = 118180
- 137 + 118043 = 118180
- 191 + 117989 = 118180
- 263 + 117917 = 118180
- 269 + 117911 = 118180
- 281 + 117899 = 118180
Showing the first eight; more decompositions exist.
