Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129496, here are decompositions:
- 5 + 129491 = 129496
- 47 + 129449 = 129496
- 53 + 129443 = 129496
- 149 + 129347 = 129496
- 233 + 129263 = 129496
- 383 + 129113 = 129496
- 503 + 128993 = 129496
- 509 + 128987 = 129496
Showing the first eight; more decompositions exist.
