Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20952, here are decompositions:
- 5 + 20947 = 20952
- 13 + 20939 = 20952
- 23 + 20929 = 20952
- 31 + 20921 = 20952
- 53 + 20899 = 20952
- 73 + 20879 = 20952
- 79 + 20873 = 20952
- 103 + 20849 = 20952
Showing the first eight; more decompositions exist.
