Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508640, here are decompositions:
- 13 + 33508627 = 33508640
- 223 + 33508417 = 33508640
- 307 + 33508333 = 33508640
- 349 + 33508291 = 33508640
- 379 + 33508261 = 33508640
- 421 + 33508219 = 33508640
- 457 + 33508183 = 33508640
- 727 + 33507913 = 33508640
Showing the first eight; more decompositions exist.
