Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20934, here are decompositions:
- 5 + 20929 = 20934
- 13 + 20921 = 20934
- 31 + 20903 = 20934
- 37 + 20897 = 20934
- 47 + 20887 = 20934
- 61 + 20873 = 20934
- 127 + 20807 = 20934
- 163 + 20771 = 20934
Showing the first eight; more decompositions exist.
