Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91886, here are decompositions:
- 13 + 91873 = 91886
- 19 + 91867 = 91886
- 73 + 91813 = 91886
- 79 + 91807 = 91886
- 313 + 91573 = 91886
- 373 + 91513 = 91886
- 433 + 91453 = 91886
- 463 + 91423 = 91886
Showing the first eight; more decompositions exist.
