Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129764, here are decompositions:
- 7 + 129757 = 129764
- 31 + 129733 = 129764
- 157 + 129607 = 129764
- 211 + 129553 = 129764
- 307 + 129457 = 129764
- 487 + 129277 = 129764
- 541 + 129223 = 129764
- 571 + 129193 = 129764
Showing the first eight; more decompositions exist.
