Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20366, here are decompositions:
- 7 + 20359 = 20366
- 13 + 20353 = 20366
- 19 + 20347 = 20366
- 43 + 20323 = 20366
- 79 + 20287 = 20366
- 97 + 20269 = 20366
- 193 + 20173 = 20366
- 223 + 20143 = 20366
Showing the first eight; more decompositions exist.
