Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521664, here are decompositions:
- 17 + 33521647 = 33521664
- 41 + 33521623 = 33521664
- 181 + 33521483 = 33521664
- 193 + 33521471 = 33521664
- 227 + 33521437 = 33521664
- 233 + 33521431 = 33521664
- 263 + 33521401 = 33521664
- 271 + 33521393 = 33521664
Showing the first eight; more decompositions exist.
