Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40068, here are decompositions:
- 5 + 40063 = 40068
- 29 + 40039 = 40068
- 31 + 40037 = 40068
- 37 + 40031 = 40068
- 59 + 40009 = 40068
- 79 + 39989 = 40068
- 89 + 39979 = 40068
- 97 + 39971 = 40068
Showing the first eight; more decompositions exist.
