Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129292, here are decompositions:
- 3 + 129289 = 129292
- 5 + 129287 = 129292
- 11 + 129281 = 129292
- 29 + 129263 = 129292
- 71 + 129221 = 129292
- 83 + 129209 = 129292
- 173 + 129119 = 129292
- 179 + 129113 = 129292
Showing the first eight; more decompositions exist.
