Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001888, here are decompositions:

  • 67 + 1001821 = 1001888
  • 79 + 1001809 = 1001888
  • 229 + 1001659 = 1001888
  • 337 + 1001551 = 1001888
  • 397 + 1001491 = 1001888
  • 421 + 1001467 = 1001888
  • 457 + 1001431 = 1001888
  • 487 + 1001401 = 1001888

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 1,001,888 and was likely granted around 1911.

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