Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28936, here are decompositions:
- 3 + 28933 = 28936
- 233 + 28703 = 28936
- 239 + 28697 = 28936
- 293 + 28643 = 28936
- 317 + 28619 = 28936
- 389 + 28547 = 28936
- 419 + 28517 = 28936
- 443 + 28493 = 28936
Showing the first eight; more decompositions exist.
