Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129704, here are decompositions:
- 61 + 129643 = 129704
- 73 + 129631 = 129704
- 97 + 129607 = 129704
- 151 + 129553 = 129704
- 577 + 129127 = 129704
- 607 + 129097 = 129704
- 643 + 129061 = 129704
- 733 + 128971 = 129704
Showing the first eight; more decompositions exist.
