Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005800, here are decompositions:

  • 139 + 1005661 = 1005800
  • 157 + 1005643 = 1005800
  • 163 + 1005637 = 1005800
  • 181 + 1005619 = 1005800
  • 307 + 1005493 = 1005800
  • 373 + 1005427 = 1005800
  • 409 + 1005391 = 1005800
  • 487 + 1005313 = 1005800

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 1,005,800 and was likely granted around 1911.

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