Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38938, here are decompositions:
- 5 + 38933 = 38938
- 17 + 38921 = 38938
- 47 + 38891 = 38938
- 71 + 38867 = 38938
- 191 + 38747 = 38938
- 227 + 38711 = 38938
- 239 + 38699 = 38938
- 269 + 38669 = 38938
Showing the first eight; more decompositions exist.
