Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000842, here are decompositions:

  • 13 + 1000829 = 1000842
  • 79 + 1000763 = 1000842
  • 151 + 1000691 = 1000842
  • 163 + 1000679 = 1000842
  • 173 + 1000669 = 1000842
  • 191 + 1000651 = 1000842
  • 223 + 1000619 = 1000842
  • 233 + 1000609 = 1000842

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 1,000,842 and was likely granted around 1911.

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