Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40032, here are decompositions:
- 19 + 40013 = 40032
- 23 + 40009 = 40032
- 43 + 39989 = 40032
- 53 + 39979 = 40032
- 61 + 39971 = 40032
- 79 + 39953 = 40032
- 103 + 39929 = 40032
- 131 + 39901 = 40032
Showing the first eight; more decompositions exist.
