Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4786, here are decompositions:
- 3 + 4783 = 4786
- 53 + 4733 = 4786
- 83 + 4703 = 4786
- 107 + 4679 = 4786
- 113 + 4673 = 4786
- 137 + 4649 = 4786
- 149 + 4637 = 4786
- 239 + 4547 = 4786
Showing the first eight; more decompositions exist.
