Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98820, here are decompositions:
- 11 + 98809 = 98820
- 13 + 98807 = 98820
- 19 + 98801 = 98820
- 41 + 98779 = 98820
- 47 + 98773 = 98820
- 83 + 98737 = 98820
- 89 + 98731 = 98820
- 103 + 98717 = 98820
Showing the first eight; more decompositions exist.
