Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20976, here are decompositions:
- 13 + 20963 = 20976
- 17 + 20959 = 20976
- 29 + 20947 = 20976
- 37 + 20939 = 20976
- 47 + 20929 = 20976
- 73 + 20903 = 20976
- 79 + 20897 = 20976
- 89 + 20887 = 20976
Showing the first eight; more decompositions exist.
