Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000838, here are decompositions:

  • 61 + 1000777 = 1000838
  • 199 + 1000639 = 1000838
  • 229 + 1000609 = 1000838
  • 331 + 1000507 = 1000838
  • 409 + 1000429 = 1000838
  • 457 + 1000381 = 1000838
  • 547 + 1000291 = 1000838
  • 607 + 1000231 = 1000838

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 1,000,838 and was likely granted around 1911.

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