Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33158, here are decompositions:
- 7 + 33151 = 33158
- 67 + 33091 = 33158
- 109 + 33049 = 33158
- 241 + 32917 = 33158
- 271 + 32887 = 33158
- 379 + 32779 = 33158
- 409 + 32749 = 33158
- 439 + 32719 = 33158
Showing the first eight; more decompositions exist.
