Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27288, here are decompositions:
- 5 + 27283 = 27288
- 7 + 27281 = 27288
- 11 + 27277 = 27288
- 17 + 27271 = 27288
- 29 + 27259 = 27288
- 47 + 27241 = 27288
- 97 + 27191 = 27288
- 109 + 27179 = 27288
Showing the first eight; more decompositions exist.
