Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129826, here are decompositions:
- 23 + 129803 = 129826
- 89 + 129737 = 129826
- 107 + 129719 = 129826
- 197 + 129629 = 129826
- 233 + 129593 = 129826
- 239 + 129587 = 129826
- 293 + 129533 = 129826
- 317 + 129509 = 129826
Showing the first eight; more decompositions exist.
