Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43806, here are decompositions:
- 5 + 43801 = 43806
- 13 + 43793 = 43806
- 17 + 43789 = 43806
- 19 + 43787 = 43806
- 23 + 43783 = 43806
- 29 + 43777 = 43806
- 47 + 43759 = 43806
- 53 + 43753 = 43806
Showing the first eight; more decompositions exist.
