Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83920, here are decompositions:
- 17 + 83903 = 83920
- 29 + 83891 = 83920
- 47 + 83873 = 83920
- 107 + 83813 = 83920
- 257 + 83663 = 83920
- 281 + 83639 = 83920
- 311 + 83609 = 83920
- 359 + 83561 = 83920
Showing the first eight; more decompositions exist.
