Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40020, here are decompositions:
- 7 + 40013 = 40020
- 11 + 40009 = 40020
- 31 + 39989 = 40020
- 37 + 39983 = 40020
- 41 + 39979 = 40020
- 67 + 39953 = 40020
- 83 + 39937 = 40020
- 137 + 39883 = 40020
Showing the first eight; more decompositions exist.
