Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65568, here are decompositions:
- 5 + 65563 = 65568
- 11 + 65557 = 65568
- 17 + 65551 = 65568
- 29 + 65539 = 65568
- 31 + 65537 = 65568
- 47 + 65521 = 65568
- 71 + 65497 = 65568
- 89 + 65479 = 65568
Showing the first eight; more decompositions exist.
