Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33473640, here are decompositions:
- 37 + 33473603 = 33473640
- 41 + 33473599 = 33473640
- 47 + 33473593 = 33473640
- 89 + 33473551 = 33473640
- 97 + 33473543 = 33473640
- 157 + 33473483 = 33473640
- 173 + 33473467 = 33473640
- 191 + 33473449 = 33473640
Showing the first eight; more decompositions exist.
