Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33128, here are decompositions:
- 37 + 33091 = 33128
- 79 + 33049 = 33128
- 157 + 32971 = 33128
- 211 + 32917 = 33128
- 241 + 32887 = 33128
- 331 + 32797 = 33128
- 349 + 32779 = 33128
- 379 + 32749 = 33128
Showing the first eight; more decompositions exist.
