Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40080, here are decompositions:
- 17 + 40063 = 40080
- 41 + 40039 = 40080
- 43 + 40037 = 40080
- 67 + 40013 = 40080
- 71 + 40009 = 40080
- 97 + 39983 = 40080
- 101 + 39979 = 40080
- 109 + 39971 = 40080
Showing the first eight; more decompositions exist.
