Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189328, here are decompositions:
- 17 + 189311 = 189328
- 71 + 189257 = 189328
- 89 + 189239 = 189328
- 179 + 189149 = 189328
- 311 + 189017 = 189328
- 317 + 189011 = 189328
- 389 + 188939 = 189328
- 401 + 188927 = 189328
Showing the first eight; more decompositions exist.
