Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43656, here are decompositions:
- 5 + 43651 = 43656
- 7 + 43649 = 43656
- 23 + 43633 = 43656
- 29 + 43627 = 43656
- 43 + 43613 = 43656
- 47 + 43609 = 43656
- 59 + 43597 = 43656
- 79 + 43577 = 43656
Showing the first eight; more decompositions exist.
