Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4874, here are decompositions:
- 3 + 4871 = 4874
- 13 + 4861 = 4874
- 43 + 4831 = 4874
- 61 + 4813 = 4874
- 73 + 4801 = 4874
- 151 + 4723 = 4874
- 211 + 4663 = 4874
- 223 + 4651 = 4874
Showing the first eight; more decompositions exist.
