Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40056, here are decompositions:
- 17 + 40039 = 40056
- 19 + 40037 = 40056
- 43 + 40013 = 40056
- 47 + 40009 = 40056
- 67 + 39989 = 40056
- 73 + 39983 = 40056
- 103 + 39953 = 40056
- 127 + 39929 = 40056
Showing the first eight; more decompositions exist.
