Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85918, here are decompositions:
- 29 + 85889 = 85918
- 71 + 85847 = 85918
- 89 + 85829 = 85918
- 101 + 85817 = 85918
- 137 + 85781 = 85918
- 167 + 85751 = 85918
- 227 + 85691 = 85918
- 251 + 85667 = 85918
Showing the first eight; more decompositions exist.
