Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19434, here are decompositions:
- 5 + 19429 = 19434
- 7 + 19427 = 19434
- 11 + 19423 = 19434
- 13 + 19421 = 19434
- 17 + 19417 = 19434
- 31 + 19403 = 19434
- 43 + 19391 = 19434
- 47 + 19387 = 19434
Showing the first eight; more decompositions exist.
