Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20412, here are decompositions:
- 5 + 20407 = 20412
- 13 + 20399 = 20412
- 19 + 20393 = 20412
- 23 + 20389 = 20412
- 43 + 20369 = 20412
- 53 + 20359 = 20412
- 59 + 20353 = 20412
- 71 + 20341 = 20412
Showing the first eight; more decompositions exist.
