Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43686, here are decompositions:
- 17 + 43669 = 43686
- 37 + 43649 = 43686
- 53 + 43633 = 43686
- 59 + 43627 = 43686
- 73 + 43613 = 43686
- 79 + 43607 = 43686
- 89 + 43597 = 43686
- 107 + 43579 = 43686
Showing the first eight; more decompositions exist.
