Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12288, here are decompositions:
- 7 + 12281 = 12288
- 11 + 12277 = 12288
- 19 + 12269 = 12288
- 37 + 12251 = 12288
- 47 + 12241 = 12288
- 61 + 12227 = 12288
- 127 + 12161 = 12288
- 131 + 12157 = 12288
Showing the first eight; more decompositions exist.
