Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129604, here are decompositions:
- 11 + 129593 = 129604
- 17 + 129587 = 129604
- 23 + 129581 = 129604
- 71 + 129533 = 129604
- 107 + 129497 = 129604
- 113 + 129491 = 129604
- 257 + 129347 = 129604
- 263 + 129341 = 129604
Showing the first eight; more decompositions exist.
