Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128176, here are decompositions:
- 3 + 128173 = 128176
- 17 + 128159 = 128176
- 23 + 128153 = 128176
- 29 + 128147 = 128176
- 179 + 127997 = 128176
- 197 + 127979 = 128176
- 263 + 127913 = 128176
- 317 + 127859 = 128176
Showing the first eight; more decompositions exist.
