Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40036, here are decompositions:
- 5 + 40031 = 40036
- 23 + 40013 = 40036
- 47 + 39989 = 40036
- 53 + 39983 = 40036
- 83 + 39953 = 40036
- 107 + 39929 = 40036
- 149 + 39887 = 40036
- 167 + 39869 = 40036
Showing the first eight; more decompositions exist.
