Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001680, here are decompositions:

  • 11 + 1001669 = 1001680
  • 41 + 1001639 = 1001680
  • 59 + 1001621 = 1001680
  • 131 + 1001549 = 1001680
  • 149 + 1001531 = 1001680
  • 179 + 1001501 = 1001680
  • 233 + 1001447 = 1001680
  • 269 + 1001411 = 1001680

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 1,001,680 and was likely granted around 1911.

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