Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80850, here are decompositions:
- 17 + 80833 = 80850
- 19 + 80831 = 80850
- 31 + 80819 = 80850
- 41 + 80809 = 80850
- 47 + 80803 = 80850
- 61 + 80789 = 80850
- 67 + 80783 = 80850
- 71 + 80779 = 80850
Showing the first eight; more decompositions exist.
