Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009856, here are decompositions:

  • 13 + 1009843 = 1009856
  • 19 + 1009837 = 1009856
  • 37 + 1009819 = 1009856
  • 109 + 1009747 = 1009856
  • 229 + 1009627 = 1009856
  • 283 + 1009573 = 1009856
  • 349 + 1009507 = 1009856
  • 373 + 1009483 = 1009856

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 1,009,856 and was likely granted around 1911.

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