Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4894, here are decompositions:
- 5 + 4889 = 4894
- 17 + 4877 = 4894
- 23 + 4871 = 4894
- 101 + 4793 = 4894
- 107 + 4787 = 4894
- 173 + 4721 = 4894
- 191 + 4703 = 4894
- 251 + 4643 = 4894
Showing the first eight; more decompositions exist.
