Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129534, here are decompositions:
- 5 + 129529 = 129534
- 7 + 129527 = 129534
- 17 + 129517 = 129534
- 37 + 129497 = 129534
- 43 + 129491 = 129534
- 73 + 129461 = 129534
- 131 + 129403 = 129534
- 173 + 129361 = 129534
Showing the first eight; more decompositions exist.
