Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17280, here are decompositions:
- 23 + 17257 = 17280
- 41 + 17239 = 17280
- 71 + 17209 = 17280
- 73 + 17207 = 17280
- 89 + 17191 = 17280
- 97 + 17183 = 17280
- 113 + 17167 = 17280
- 157 + 17123 = 17280
Showing the first eight; more decompositions exist.
