Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003808, here are decompositions:

  • 37 + 1003771 = 1003808
  • 61 + 1003747 = 1003808
  • 67 + 1003741 = 1003808
  • 79 + 1003729 = 1003808
  • 97 + 1003711 = 1003808
  • 181 + 1003627 = 1003808
  • 199 + 1003609 = 1003808
  • 397 + 1003411 = 1003808

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 1,003,808 and was likely granted around 1911.

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