Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28474, here are decompositions:
- 11 + 28463 = 28474
- 41 + 28433 = 28474
- 71 + 28403 = 28474
- 167 + 28307 = 28474
- 191 + 28283 = 28474
- 197 + 28277 = 28474
- 263 + 28211 = 28474
- 293 + 28181 = 28474
Showing the first eight; more decompositions exist.
