Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38666, here are decompositions:
- 13 + 38653 = 38666
- 37 + 38629 = 38666
- 73 + 38593 = 38666
- 97 + 38569 = 38666
- 109 + 38557 = 38666
- 337 + 38329 = 38666
- 349 + 38317 = 38666
- 367 + 38299 = 38666
Showing the first eight; more decompositions exist.
