Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80842, here are decompositions:
- 11 + 80831 = 80842
- 23 + 80819 = 80842
- 53 + 80789 = 80842
- 59 + 80783 = 80842
- 173 + 80669 = 80842
- 191 + 80651 = 80842
- 239 + 80603 = 80842
- 353 + 80489 = 80842
Showing the first eight; more decompositions exist.
