Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543720, here are decompositions:
- 11 + 33543709 = 33543720
- 31 + 33543689 = 33543720
- 47 + 33543673 = 33543720
- 59 + 33543661 = 33543720
- 71 + 33543649 = 33543720
- 79 + 33543641 = 33543720
- 137 + 33543583 = 33543720
- 167 + 33543553 = 33543720
Showing the first eight; more decompositions exist.
