Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20576, here are decompositions:
- 13 + 20563 = 20576
- 43 + 20533 = 20576
- 67 + 20509 = 20576
- 97 + 20479 = 20576
- 223 + 20353 = 20576
- 229 + 20347 = 20576
- 307 + 20269 = 20576
- 433 + 20143 = 20576
Showing the first eight; more decompositions exist.
