Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39638, here are decompositions:
- 7 + 39631 = 39638
- 19 + 39619 = 39638
- 31 + 39607 = 39638
- 97 + 39541 = 39638
- 127 + 39511 = 39638
- 139 + 39499 = 39638
- 199 + 39439 = 39638
- 229 + 39409 = 39638
Showing the first eight; more decompositions exist.
