Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20454, here are decompositions:
- 11 + 20443 = 20454
- 13 + 20441 = 20454
- 23 + 20431 = 20454
- 43 + 20411 = 20454
- 47 + 20407 = 20454
- 61 + 20393 = 20454
- 97 + 20357 = 20454
- 101 + 20353 = 20454
Showing the first eight; more decompositions exist.
