Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6656, here are decompositions:
- 3 + 6653 = 6656
- 19 + 6637 = 6656
- 37 + 6619 = 6656
- 79 + 6577 = 6656
- 103 + 6553 = 6656
- 109 + 6547 = 6656
- 127 + 6529 = 6656
- 229 + 6427 = 6656
Showing the first eight; more decompositions exist.
