Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133456, here are decompositions:
- 5 + 133451 = 133456
- 17 + 133439 = 133456
- 53 + 133403 = 133456
- 107 + 133349 = 133456
- 137 + 133319 = 133456
- 173 + 133283 = 133456
- 179 + 133277 = 133456
- 269 + 133187 = 133456
Showing the first eight; more decompositions exist.
