Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65464, here are decompositions:
- 17 + 65447 = 65464
- 41 + 65423 = 65464
- 71 + 65393 = 65464
- 83 + 65381 = 65464
- 107 + 65357 = 65464
- 137 + 65327 = 65464
- 197 + 65267 = 65464
- 251 + 65213 = 65464
Showing the first eight; more decompositions exist.
