Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128022, here are decompositions:
- 43 + 127979 = 128022
- 71 + 127951 = 128022
- 101 + 127921 = 128022
- 109 + 127913 = 128022
- 149 + 127873 = 128022
- 163 + 127859 = 128022
- 173 + 127849 = 128022
- 179 + 127843 = 128022
Showing the first eight; more decompositions exist.
