Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4928, here are decompositions:
- 19 + 4909 = 4928
- 67 + 4861 = 4928
- 97 + 4831 = 4928
- 127 + 4801 = 4928
- 139 + 4789 = 4928
- 199 + 4729 = 4928
- 271 + 4657 = 4928
- 277 + 4651 = 4928
Showing the first eight; more decompositions exist.
