Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000686, here are decompositions:

  • 7 + 1000679 = 1000686
  • 17 + 1000669 = 1000686
  • 19 + 1000667 = 1000686
  • 47 + 1000639 = 1000686
  • 67 + 1000619 = 1000686
  • 97 + 1000589 = 1000686
  • 107 + 1000579 = 1000686
  • 109 + 1000577 = 1000686

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 1,000,686 and was likely granted around 1911.

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