Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80886, here are decompositions:
- 23 + 80863 = 80886
- 37 + 80849 = 80886
- 53 + 80833 = 80886
- 67 + 80819 = 80886
- 83 + 80803 = 80886
- 97 + 80789 = 80886
- 103 + 80783 = 80886
- 107 + 80779 = 80886
Showing the first eight; more decompositions exist.
