Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001812, here are decompositions:

  • 3 + 1001809 = 1001812
  • 5 + 1001807 = 1001812
  • 11 + 1001801 = 1001812
  • 29 + 1001783 = 1001812
  • 89 + 1001723 = 1001812
  • 173 + 1001639 = 1001812
  • 191 + 1001621 = 1001812
  • 263 + 1001549 = 1001812

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 1,001,812 and was likely granted around 1911.

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