Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28354, here are decompositions:
- 3 + 28351 = 28354
- 5 + 28349 = 28354
- 47 + 28307 = 28354
- 71 + 28283 = 28354
- 173 + 28181 = 28354
- 191 + 28163 = 28354
- 257 + 28097 = 28354
- 353 + 28001 = 28354
Showing the first eight; more decompositions exist.
