Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4782, here are decompositions:
- 23 + 4759 = 4782
- 31 + 4751 = 4782
- 53 + 4729 = 4782
- 59 + 4723 = 4782
- 61 + 4721 = 4782
- 79 + 4703 = 4782
- 103 + 4679 = 4782
- 109 + 4673 = 4782
Showing the first eight; more decompositions exist.
