Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38998, here are decompositions:
- 5 + 38993 = 38998
- 107 + 38891 = 38998
- 131 + 38867 = 38998
- 137 + 38861 = 38998
- 251 + 38747 = 38998
- 269 + 38729 = 38998
- 347 + 38651 = 38998
- 359 + 38639 = 38998
Showing the first eight; more decompositions exist.
