Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001918, here are decompositions:

  • 7 + 1001911 = 1001918
  • 79 + 1001839 = 1001918
  • 97 + 1001821 = 1001918
  • 109 + 1001809 = 1001918
  • 331 + 1001587 = 1001918
  • 349 + 1001569 = 1001918
  • 367 + 1001551 = 1001918
  • 487 + 1001431 = 1001918

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 1,001,918 and was likely granted around 1911.

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