Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129794, here are decompositions:
- 31 + 129763 = 129794
- 37 + 129757 = 129794
- 61 + 129733 = 129794
- 151 + 129643 = 129794
- 163 + 129631 = 129794
- 241 + 129553 = 129794
- 277 + 129517 = 129794
- 337 + 129457 = 129794
Showing the first eight; more decompositions exist.
