Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4838, here are decompositions:
- 7 + 4831 = 4838
- 37 + 4801 = 4838
- 79 + 4759 = 4838
- 109 + 4729 = 4838
- 181 + 4657 = 4838
- 199 + 4639 = 4838
- 241 + 4597 = 4838
- 271 + 4567 = 4838
Showing the first eight; more decompositions exist.
