Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28426, here are decompositions:
- 17 + 28409 = 28426
- 23 + 28403 = 28426
- 107 + 28319 = 28426
- 137 + 28289 = 28426
- 149 + 28277 = 28426
- 197 + 28229 = 28426
- 263 + 28163 = 28426
- 317 + 28109 = 28426
Showing the first eight; more decompositions exist.
