Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133328, here are decompositions:
- 7 + 133321 = 133328
- 67 + 133261 = 133328
- 127 + 133201 = 133328
- 211 + 133117 = 133328
- 241 + 133087 = 133328
- 277 + 133051 = 133328
- 367 + 132961 = 133328
- 379 + 132949 = 133328
Showing the first eight; more decompositions exist.
