Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83820, here are decompositions:
- 7 + 83813 = 83820
- 29 + 83791 = 83820
- 43 + 83777 = 83820
- 47 + 83773 = 83820
- 59 + 83761 = 83820
- 83 + 83737 = 83820
- 101 + 83719 = 83820
- 103 + 83717 = 83820
Showing the first eight; more decompositions exist.
