Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83666, here are decompositions:
- 3 + 83663 = 83666
- 13 + 83653 = 83666
- 103 + 83563 = 83666
- 109 + 83557 = 83666
- 223 + 83443 = 83666
- 229 + 83437 = 83666
- 277 + 83389 = 83666
- 283 + 83383 = 83666
Showing the first eight; more decompositions exist.
