Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129676, here are decompositions:
- 5 + 129671 = 129676
- 47 + 129629 = 129676
- 83 + 129593 = 129676
- 89 + 129587 = 129676
- 137 + 129539 = 129676
- 149 + 129527 = 129676
- 167 + 129509 = 129676
- 179 + 129497 = 129676
Showing the first eight; more decompositions exist.
