Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521440, here are decompositions:
- 3 + 33521437 = 33521440
- 23 + 33521417 = 33521440
- 47 + 33521393 = 33521440
- 263 + 33521177 = 33521440
- 269 + 33521171 = 33521440
- 353 + 33521087 = 33521440
- 383 + 33521057 = 33521440
- 401 + 33521039 = 33521440
Showing the first eight; more decompositions exist.
