Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28498, here are decompositions:
- 5 + 28493 = 28498
- 59 + 28439 = 28498
- 89 + 28409 = 28498
- 149 + 28349 = 28498
- 179 + 28319 = 28498
- 191 + 28307 = 28498
- 269 + 28229 = 28498
- 317 + 28181 = 28498
Showing the first eight; more decompositions exist.
