Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40026, here are decompositions:
- 13 + 40013 = 40026
- 17 + 40009 = 40026
- 37 + 39989 = 40026
- 43 + 39983 = 40026
- 47 + 39979 = 40026
- 73 + 39953 = 40026
- 89 + 39937 = 40026
- 97 + 39929 = 40026
Showing the first eight; more decompositions exist.
