Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33607728, here are decompositions:
- 17 + 33607711 = 33607728
- 29 + 33607699 = 33607728
- 31 + 33607697 = 33607728
- 109 + 33607619 = 33607728
- 181 + 33607547 = 33607728
- 199 + 33607529 = 33607728
- 239 + 33607489 = 33607728
- 257 + 33607471 = 33607728
Showing the first eight; more decompositions exist.
