Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129322, here are decompositions:
- 29 + 129293 = 129322
- 41 + 129281 = 129322
- 59 + 129263 = 129322
- 101 + 129221 = 129322
- 113 + 129209 = 129322
- 233 + 129089 = 129322
- 239 + 129083 = 129322
- 311 + 129011 = 129322
Showing the first eight; more decompositions exist.
