Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20926, here are decompositions:
- 5 + 20921 = 20926
- 23 + 20903 = 20926
- 29 + 20897 = 20926
- 47 + 20879 = 20926
- 53 + 20873 = 20926
- 137 + 20789 = 20926
- 167 + 20759 = 20926
- 173 + 20753 = 20926
Showing the first eight; more decompositions exist.
