Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129754, here are decompositions:
- 5 + 129749 = 129754
- 17 + 129737 = 129754
- 47 + 129707 = 129754
- 83 + 129671 = 129754
- 113 + 129641 = 129754
- 167 + 129587 = 129754
- 173 + 129581 = 129754
- 227 + 129527 = 129754
Showing the first eight; more decompositions exist.
