Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129384, here are decompositions:
- 5 + 129379 = 129384
- 23 + 129361 = 129384
- 37 + 129347 = 129384
- 43 + 129341 = 129384
- 71 + 129313 = 129384
- 97 + 129287 = 129384
- 103 + 129281 = 129384
- 107 + 129277 = 129384
Showing the first eight; more decompositions exist.
