Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19554, here are decompositions:
- 11 + 19543 = 19554
- 13 + 19541 = 19554
- 23 + 19531 = 19554
- 47 + 19507 = 19554
- 53 + 19501 = 19554
- 71 + 19483 = 19554
- 83 + 19471 = 19554
- 97 + 19457 = 19554
Showing the first eight; more decompositions exist.
