Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4842, here are decompositions:
- 11 + 4831 = 4842
- 29 + 4813 = 4842
- 41 + 4801 = 4842
- 43 + 4799 = 4842
- 53 + 4789 = 4842
- 59 + 4783 = 4842
- 83 + 4759 = 4842
- 109 + 4733 = 4842
Showing the first eight; more decompositions exist.
