Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65506, here are decompositions:
- 59 + 65447 = 65506
- 83 + 65423 = 65506
- 113 + 65393 = 65506
- 149 + 65357 = 65506
- 179 + 65327 = 65506
- 197 + 65309 = 65506
- 239 + 65267 = 65506
- 293 + 65213 = 65506
Showing the first eight; more decompositions exist.
