Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189118, here are decompositions:
- 101 + 189017 = 189118
- 107 + 189011 = 189118
- 179 + 188939 = 189118
- 191 + 188927 = 189118
- 227 + 188891 = 189118
- 257 + 188861 = 189118
- 317 + 188801 = 189118
- 389 + 188729 = 189118
Showing the first eight; more decompositions exist.
