Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001786, here are decompositions:

  • 3 + 1001783 = 1001786
  • 43 + 1001743 = 1001786
  • 73 + 1001713 = 1001786
  • 103 + 1001683 = 1001786
  • 127 + 1001659 = 1001786
  • 157 + 1001629 = 1001786
  • 193 + 1001593 = 1001786
  • 199 + 1001587 = 1001786

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 1,001,786 and was likely granted around 1911.

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