Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65530, here are decompositions:
- 11 + 65519 = 65530
- 83 + 65447 = 65530
- 107 + 65423 = 65530
- 137 + 65393 = 65530
- 149 + 65381 = 65530
- 173 + 65357 = 65530
- 263 + 65267 = 65530
- 317 + 65213 = 65530
Showing the first eight; more decompositions exist.
