Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27728, here are decompositions:
- 31 + 27697 = 27728
- 37 + 27691 = 27728
- 97 + 27631 = 27728
- 199 + 27529 = 27728
- 241 + 27487 = 27728
- 271 + 27457 = 27728
- 331 + 27397 = 27728
- 367 + 27361 = 27728
Showing the first eight; more decompositions exist.
