Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65666, here are decompositions:
- 19 + 65647 = 65666
- 37 + 65629 = 65666
- 67 + 65599 = 65666
- 79 + 65587 = 65666
- 103 + 65563 = 65666
- 109 + 65557 = 65666
- 127 + 65539 = 65666
- 229 + 65437 = 65666
Showing the first eight; more decompositions exist.
