Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65536, here are decompositions:
- 17 + 65519 = 65536
- 89 + 65447 = 65536
- 113 + 65423 = 65536
- 179 + 65357 = 65536
- 227 + 65309 = 65536
- 269 + 65267 = 65536
- 353 + 65183 = 65536
- 389 + 65147 = 65536
Showing the first eight; more decompositions exist.
