Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005812, here are decompositions:

  • 61 + 1005751 = 1005812
  • 103 + 1005709 = 1005812
  • 151 + 1005661 = 1005812
  • 193 + 1005619 = 1005812
  • 271 + 1005541 = 1005812
  • 331 + 1005481 = 1005812
  • 373 + 1005439 = 1005812
  • 421 + 1005391 = 1005812

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 1,005,812 and was likely granted around 1911.

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