Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20950, here are decompositions:
- 3 + 20947 = 20950
- 11 + 20939 = 20950
- 29 + 20921 = 20950
- 47 + 20903 = 20950
- 53 + 20897 = 20950
- 71 + 20879 = 20950
- 101 + 20849 = 20950
- 179 + 20771 = 20950
Showing the first eight; more decompositions exist.
