Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43720, here are decompositions:
- 3 + 43717 = 43720
- 29 + 43691 = 43720
- 59 + 43661 = 43720
- 71 + 43649 = 43720
- 107 + 43613 = 43720
- 113 + 43607 = 43720
- 179 + 43541 = 43720
- 233 + 43487 = 43720
Showing the first eight; more decompositions exist.
