Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008686, here are decompositions:

  • 73 + 1008613 = 1008686
  • 79 + 1008607 = 1008686
  • 97 + 1008589 = 1008686
  • 139 + 1008547 = 1008686
  • 193 + 1008493 = 1008686
  • 277 + 1008409 = 1008686
  • 307 + 1008379 = 1008686
  • 313 + 1008373 = 1008686

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,008,686 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
