Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20954, here are decompositions:
- 7 + 20947 = 20954
- 67 + 20887 = 20954
- 97 + 20857 = 20954
- 181 + 20773 = 20954
- 211 + 20743 = 20954
- 223 + 20731 = 20954
- 313 + 20641 = 20954
- 421 + 20533 = 20954
Showing the first eight; more decompositions exist.
