Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003806, here are decompositions:

  • 19 + 1003787 = 1003806
  • 43 + 1003763 = 1003806
  • 53 + 1003753 = 1003806
  • 59 + 1003747 = 1003806
  • 73 + 1003733 = 1003806
  • 113 + 1003693 = 1003806
  • 127 + 1003679 = 1003806
  • 179 + 1003627 = 1003806

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 1,003,806 and was likely granted around 1911.

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