Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20948, here are decompositions:
- 19 + 20929 = 20948
- 61 + 20887 = 20948
- 139 + 20809 = 20948
- 199 + 20749 = 20948
- 229 + 20719 = 20948
- 241 + 20707 = 20948
- 307 + 20641 = 20948
- 337 + 20611 = 20948
Showing the first eight; more decompositions exist.
