Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28528, here are decompositions:
- 11 + 28517 = 28528
- 29 + 28499 = 28528
- 89 + 28439 = 28528
- 179 + 28349 = 28528
- 239 + 28289 = 28528
- 251 + 28277 = 28528
- 317 + 28211 = 28528
- 347 + 28181 = 28528
Showing the first eight; more decompositions exist.
