Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4818, here are decompositions:
- 5 + 4813 = 4818
- 17 + 4801 = 4818
- 19 + 4799 = 4818
- 29 + 4789 = 4818
- 31 + 4787 = 4818
- 59 + 4759 = 4818
- 67 + 4751 = 4818
- 89 + 4729 = 4818
Showing the first eight; more decompositions exist.
