Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133408, here are decompositions:
- 5 + 133403 = 133408
- 17 + 133391 = 133408
- 29 + 133379 = 133408
- 59 + 133349 = 133408
- 71 + 133337 = 133408
- 89 + 133319 = 133408
- 131 + 133277 = 133408
- 137 + 133271 = 133408
Showing the first eight; more decompositions exist.
