Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81848, here are decompositions:
- 31 + 81817 = 81848
- 79 + 81769 = 81848
- 181 + 81667 = 81848
- 199 + 81649 = 81848
- 211 + 81637 = 81848
- 229 + 81619 = 81848
- 331 + 81517 = 81848
- 409 + 81439 = 81848
Showing the first eight; more decompositions exist.
