Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28468, here are decompositions:
- 5 + 28463 = 28468
- 29 + 28439 = 28468
- 59 + 28409 = 28468
- 149 + 28319 = 28468
- 179 + 28289 = 28468
- 191 + 28277 = 28468
- 239 + 28229 = 28468
- 257 + 28211 = 28468
Showing the first eight; more decompositions exist.
